[0238] Embodiment 1

[0239] As Figures 1 to 11 shown, this embodiment discloses a developing cartridge 1, which can be detachably combined with a drum assembly and can be detachably installed together with the drum assembly into an image forming apparatus having a detecting member and an identifying contact.

[0240] As shown Figures 1 to 3 in FIG. 1, the developing cartridge 1 includes a cartridge body 10. An accommodation cavity is provided inside the cartridge body 10 for accommodating a developer. The cartridge body 10 has a first end 11 and a second end 12 in a first direction, a third end 13 and a fourth end 14 in a second direction, and a fifth end 15 and a sixth end 16 in a third direction. The first direction, the second direction, and the third direction intersect with each other, preferably being orthogonal to each other.

[0241] As an embodiment of the first direction, the second direction, and the third direction, the first direction is the left - right direction, the second direction is the front - back direction, and the third direction is the up - down direction.

[0242] A developing roller 131, a powder feeding roller, and a stirring frame are rotatably installed in the accommodation cavity of the cartridge body 10. The developing roller 131, the powder feeding roller, and the stirring frame rotate around a developing roller axis, a powder feeding roller axis, and a stirring frame axis extending in the first direction respectively. In the front - back direction, the developing roller 131 is located at the third end 13 (i.e., the front end), and a handle 141 for the user to hold is provided at the fourth end 14 (i.e., the back end).

[0243] As shown Figure 2 in FIG. 2, a driving part 21 is provided at the first end 11. The driving part 21 rotates by receiving external power. The rotation axis of the driving part 21 extends in the first direction. The driving part 21 includes a power receiving part 211 and a driving gear 212, which are integrally formed coaxially or assembled separately. The power receiving part 211 is used to receive the power provided by the image forming apparatus. In the first direction, the driving gear 212 is more to the left than the power receiving part 211.

[0244] As shown Figure 4 in FIG. 3, the developing cartridge 1 further includes a triggering part 41 for contacting a detecting part and driving the detecting part to move to trigger the detecting part, a power supply component (electrode) for receiving the electric energy provided by the image forming apparatus and transmitting the electric energy to the developing roller 131 and / or the powder feeding roller, and an identification component for storing information related to the developing cartridge 1 (model, capacity, life, etc.) and being readable by contacting an identification terminal in the image forming apparatus to read the stored information.

[0245] The power supply component is provided at the second end 12 of the cartridge body 10, and the power supply component includes an electric energy receiving surface 61 for contacting a power supply terminal to receive the electric energy provided by the image forming apparatus. The electric energy receiving surface 61 is located at the second end 12.

[0246] The identification component includes a storage medium and an electric contact surface 51. The electric contact surface 51 is electrically connected to the storage medium. The electric contact surface 51 is provided at the first end 11. The storage medium stores information about the developing cartridge 1, and the electric contact surface 51 directly contacts the identification terminal to transmit the information in the storage medium to the image forming apparatus.

[0247] As shownFigure 2 As shown, a driving assembly is provided on the developing box 1, and the driving assembly is used to transmit power to the developing roller 131, the powder feeding roller, and the stirring frame, so that the developing roller 131, the powder feeding roller, and the stirring frame rotate. The driving assembly includes:

[0248] A developing gear 22 is coaxially fixedly mounted on the right end of the developing roller 131, a powder feeding gear 23 is coaxially fixedly mounted on the right end of the powder feeding roller, a stirring gear 24 is coaxially fixedly mounted on the right end of the stirring frame, and an idler gear 25 is rotatably mounted on the first end 11. The developing gear 22, the powder feeding gear 23 and the idler gear 25 are meshed with the driving gear 212 to receive power, and the stirring gear 24 is meshed with the idler gear 25 to receive power. This embodiment does not limit the number of idlers and the meshing relationship between the gears, and can be set according to actual needs.

[0249] like Figures 1 - 6 As shown, a transmission assembly is provided on the developing box 1, and the transmission assembly is used to transmit power to the trigger part 41, so that the trigger part 41 can move between the detection position and the non-detection position. The transmission assembly is connected to the driving assembly to obtain power, and transmits the power to the detected part 4 to make it move.

[0250] The transmission assembly includes a plurality of rotating members, and the rotation axes of at least some of the rotating members intersect with the first direction and the second direction, preferably the rotation axes of at least three rotating members intersect with the first direction, and preferably the rotation axes of 8 to 16 rotating members intersect with the first direction. The transmission assembly includes: a first rotating member 31, a second rotating member 32, a third rotating member 33, a fourth rotating member 34, and a transmission rotating member 35. In this embodiment, the first rotating member 31, the second rotating member 32, the third rotating member 33, the fourth rotating member 34, and the transmission rotating member 35 are respectively implemented as a first transmission gear, a second transmission gear, a third transmission gear, a fourth transmission gear, and a fifth transmission gear.

[0251] like Figure 2 and Figure 7 As shown, the first rotating member 31 (first transmission gear) is rotatably mounted on the first end 11 and the rotation axis is parallel to the first direction. The first rotating member 31 meshes with the idler 25 to receive power. The first rotating member 31 includes a first tooth portion 311 and a second tooth portion 312 arranged coaxially. The first tooth portion 311 is further to the right than the second tooth portion 312, and the first tooth portion 311 meshes with the idler 25. In this embodiment, the first tooth portion 311 is a helical tooth or a straight tooth, and the second tooth portion 312 is a bevel tooth. A missing tooth portion 3111 is also provided on the first tooth portion 311 of the first rotating member 31. When the missing tooth portion 3111 is opposite to the idler 25, the first rotating member 31 is disconnected from the idler, that is, the first rotating member 31 no longer rotates.

[0252] like Figure 1 and Figure 2As shown, the second rotating member 32 (second transmission gear) is rotatably mounted on the fifth end 15 (i.e., the upper end). The rotation axis of the second rotating member 32 preferably extends in the third direction (which may be parallel to or slightly intersect with the third direction, i.e., intersect with the first direction). The second rotating member 32 includes a third tooth portion 321 and a fourth tooth portion 322 arranged coaxially. The third tooth portion 321 meshes with the second tooth portion 312. In this embodiment, the third tooth portion 321 is a bevel gear, and the fourth tooth portion 322 is a straight gear or a helical gear. The third tooth portion 321 meshes with the second tooth portion 312 so that the second rotating member 32 receives the power transmitted by the first rotating member 31 and rotates. That is, the first rotating member 31 and the second rotating member 32 transmit power through meshing. The meshing method can be ordinary gear meshing, or cylindrical pin (pin wheel) meshing, or abutting transmission between protrusions.

[0253] As Figure 1 shown, the third rotating member 33 (third transmission gear) is rotatably mounted on the fifth end 15. The rotation axis of the third rotating member 33 extends in the third direction (which may be parallel to or slightly intersect with the third direction, i.e., intersect with the first direction). A fifth tooth portion 331 is provided on the third rotating member 33. In this embodiment, the fifth tooth portion 331 is a straight gear or a helical gear. The number of the third rotating members 33 is multiple, and the structures of the multiple third rotating members 33 are the same to simplify the component structure on the developing cartridge 1 and the composition manner of the developing cartridge 1. In this embodiment, the number of the third rotating members 33 is preferably six. The third rotating members 33 are arranged in a meshing manner from right to left on the fifth end 15 of the cartridge body 10. The rightmost third rotating member 33 can be regarded as the initial third rotating member 330, and the leftmost third rotating member 33 can be regarded as the final third rotating member 33n. The final third rotating member 33n is farther from the first end 11 than the initial third rotating member 330. The fifth tooth portion 331 of the initial third rotating member 33n meshes with the fourth tooth portion 322 of the second rotating member 32 to receive power and rotate and transmit the power to the final third rotating member 33n in sequence. The number of the third rotating members 33 can be set arbitrarily. According to different developing cartridges 1, different numbers of the third rotating members 33 are selected.

[0254] As Figure 4 and Figure 5As shown, the fourth rotating member 34 (the fourth transmission gear) is rotatably mounted on the fifth end 15. The rotation axis of the fourth rotating member 34 is parallel to the third direction (or may slightly intersect the third direction, that is, intersect the first direction). The fourth rotating member 34 includes a sixth tooth portion 341 (small tooth portion) and a seventh tooth portion 342 (large tooth portion) arranged coaxially. In the third direction, the sixth tooth portion 341 is located above the seventh tooth portion 342. In this embodiment, the sixth tooth portion 341 and the seventh tooth portion 342 are straight teeth or helical teeth. The sixth tooth portion 341 meshes with the fifth tooth portion 331 so that the fourth rotating member 34 receives the power transmitted by the third rotating member 33 and rotates. The diameter of the sixth tooth portion 341 is smaller than the diameters of the seventh tooth portion 342 and the fifth tooth portion 331, so that the rotation speed of the fourth rotating member 34 is greater than that of the third rotating member 33. In other embodiments, different numbers of fourth rotating members 34 may also be provided to further increase the rotation speed, or the seventh tooth portion 342 may be meshed with the fifth tooth portion 331, so that the speed of the fourth rotating member 34 is less than that of the third rotating member 33 to meet the requirements of different models of the developing cartridge 1.

[0255] The transmission rotating member 35 (the fifth transmission gear) is rotatably mounted on the fifth end. The rotation axis of the transmission rotating member 35 is parallel to the third direction (or may slightly intersect the third direction, that is, intersect the first direction). The transmission rotating member 35 includes a transmission tooth portion 351. The transmission tooth portion 351 is a straight tooth or a helical tooth. The transmission tooth portion 351 meshes with the seventh tooth portion 342 so that the transmission rotating member 35 receives the power transmitted by the fourth rotating member 34 and rotates. A transmission protrusion 352 is provided on the upper end surface of the transmission rotating member 35. The transmission protrusion 352 extends upward in the third direction. That is, in this embodiment, there are 9 rotating members whose rotation axes intersect the first direction. In some embodiments, at least part of the second rotating member 32, the third rotating member 33, the fourth rotating member 34, and the transmission rotating member 35 are located at the fourth end 14 and the rotation axes extend in the second direction.

[0256] As Figure 5 shown, the developing cartridge 1 further includes a detected member 4. A first pivot shaft 151 is further provided on the fifth end 15. The detected member 4 is rotatably mounted on the first pivot shaft 151 and can pivot around the first pivot shaft 151. The extending direction of the first pivot shaft 151 intersects the first direction, preferably parallel to the third direction, that is, the rotation axis of the detected member 4 is parallel to the third direction. In other embodiments, the first pivot shaft 151 may also be fixedly provided on the detected member 4, and a hole for inserting the first pivot shaft 151 is provided on the fifth end 15, which can also achieve the effect of rotatably mounting the detected member 4 on the fifth end 15.

[0257] As Figures 4 to 6As shown, the detected part 4 includes a driven part 42 located on the right side of the first pivot shaft 151 and a trigger part 41 located on the left side of the first pivot shaft 151. The trigger part 41 is integrally formed with or separately combined with the driven part 42. The trigger part 41 is located at the second end 12 and is exposed from the opening of the second cover 121 to facilitate contact with the detection part. On the lower end surface of the driven part 42, a first driven part 421, a second driven part 422, a third driven part 423, and a fourth driven part 424 are provided. The first driven part 421, the second driven part 422, the third driven part 423, and the fourth driven part 424 all protrude downward in the third direction. The second driven part 422, the third driven part 423, and the fourth driven part 424 can all be driven by the transmission protrusion 352 to drive the detected part 4 to pivot from the non-detection position to the detection position around the first pivot shaft 151, that is, the transmission rotating part 35 acts as a transmission part to drive the detected part 4 to move. The first driven part 421 is in the shape of an arc-shaped track composed of two arc-shaped ribs that are radially spaced and protrude downward. The fourth driven part 424 is connected to the upstream end of the first driven part 421 in the rotation direction of the transmission rotating part 35, and the transmission rotating part 35 rotates counterclockwise. During the process of the trigger part 41 moving from the non-detection position to the detection position, it contacts the detection part and drives the detection part to move and generate an electrical signal.

[0258] A reset elastic member 36 is also installed on the fifth end 15. One end of the reset elastic member 36 is fixedly connected to the first connection part 152 that is fixed on the fifth end 15 and protrudes upward, and the other end is fixedly connected to the second connection part 43 that is fixedly arranged on the upper end of the driven part 42 of the detected part 4 and protrudes upward. The reset elastic member 36 is used to keep the detected part 4 / trigger part 41 in the non-detection position, and the reset elastic member 36 can be an elastic member such as a tension spring.

[0259] The specific detection process is as follows:

[0260] The power receiving part 211 receives power and drives the transmission assembly through the driving gear 212. The transmission assembly then causes the transmission rotating part 35 to rotate, and the transmission protrusion 352 rotates in a circular motion along the counterclockwise direction (viewed from the top-down perspective) together with the transmission rotating part 35.

[0261] As Figure 7 and Figure 8 shown, when the transmission protrusion 352 is in the initial position, the transmission protrusion 352 is at the upstream end of the first driven part 421 in the rotation direction of the transmission rotating part 35. As the transmission protrusion 352 makes a circular motion, the transmission protrusion 352 moves within the first driven part 421, so that the detected part 4 / trigger part 41 is kept in the detection position, the detection part is kept in the triggered state and the maintained duration is T1, and the central angle corresponding to the trigger part 41 on the circle formed by the rotation trajectory of the transmission protrusion 352 is A1.

[0262] As Figure 9 shown, as the driving protrusion 352 moves in a circular motion, after the driving protrusion 352 disengages from the first driven part 421, the detected part 4 / trigger part 41 pivots clockwise to the non-detection position under the action of the reset elastic member 36.

[0263] Then, the driving protrusion 352 contacts the second driven part 422, causing the second driven part 422 to receive the power of the driving protrusion 352 and drive the detected part 4 to rotate counterclockwise, so that the trigger part 41 moves to the detection position, triggering the detector again and the maintenance time of the trigger state being T2, and the central angle subtended by the second driven part 422 on the circle formed by the rotation trajectory of the driving protrusion 352 being A2.

[0264] Then, the driving protrusion 352 disengages from the second driven part 422, and under the action of the reset elastic member 36, the detected part 4 / trigger part 41 pivots clockwise to the non-detection position.

[0265] Then, the driving protrusion 352 contacts the third driven part 423, causing the third driven part 423 to receive the power of the driving protrusion 352 and drive the detected part 4 to swing counterclockwise, so that the trigger part 41 moves to the detection position, triggering the detector again and the maintenance time of the trigger state being T3, and the central angle subtended by the third driven part 423 on the circle formed by the rotation trajectory of the driving protrusion 352 being A3.

[0266] Then, the driving protrusion 352 disengages from the third driven part 423, and under the action of the reset elastic member 36, the detected part 4 / trigger part 41 pivots clockwise to the non-detection position.

[0267] As Figure 8 and Figure 10As shown, then, the driving protrusion 352 contacts the fourth driven part 424, causing the fourth driven part 424 to receive the power of the driving protrusion 352 and drive the detected part 4 to swing counterclockwise, so that the triggering part 41 moves to the detection position, triggering the detector again and the maintenance time of the triggering state being T4. The central angle subtended by the fourth driven part 424 on the circle formed by the rotation trajectory of the driving protrusion 352 is A4, and the angle of A4 < the angles of A2 and A3 < the angle of A1. Also, since the stroke of the detected part 4 / triggering part 41 from the non-detection position to the detection position is the same each time, and the rotation speed of the driving protrusion 352 is constant, then the smaller the central angle subtended, the faster the moving speed of the detected part 4 / triggering part 41. Thus, when the driving protrusion 352 passes through the fourth driven part 424, the speed at which the triggering part 41 moves from the non-detection position to the detection position is the second speed V2, and the speed at which the triggering part 41 moves from the non-detection position to the detection position when the driving protrusion 352 passes through the second driven part 422 and the third driven part 423 is the first speed V1, and the second speed V2 is greater than the first speed V1. And because the angle of A1 is the largest, when the driving protrusion 352 contacts the first driven part 421, the time T1 for which the triggering part 41 remains in the detection position > T2, T3, T4.

[0268] As Figure 11 shown, then the first rotating part 31 rotates to the end position. At this time, the toothless part 3111 faces the idle gear 25, so that the first rotating part 31 can no longer receive power. Therefore, the transmission assembly cannot receive power, causing the second rotating part 32, the third rotating part 33, the fourth rotating part 34, and the transmission rotating part 35 to stop rotating, thus completing the detection process. In some embodiments, the toothless part can be provided on any one of the rotating parts in the transmission assembly or on the idle gear 25.

[0269] In this embodiment, the transmission assembly transmits power from the first end 11 to the second end 12 through multiple rotating parts (in the manner of multiple gears meshing), causing the triggering part 41 to trigger the detector to complete the detection. Moreover, by varying the time, speed, and number of times the triggering part 41 remains in the detection position, through the permutation and combination of the above information, different models of the developing cartridge 1 can be corresponded to, so that the detector in the image forming apparatus can detect information such as whether the developing cartridge 1 is installed, new or old, model, life, capacity, etc. based on the above information.

[0270] Those skilled in the art can change the number of times the trigger part 41 enters the detection position by changing, increasing or decreasing the first driven part 421, the second driven part 422, the third driven part 423, and the fourth driven part 424. They can change the speed and duration of the trigger part 41 entering the detection position by changing the central angles corresponding to the first driven part 421, the second driven part 422, the third driven part 423, and the fourth driven part 424.

[0271] In some embodiments, there is no need to separately provide a driving part. The developing gear 22 serves as the driving part to receive external power. Specifically, the developing gear 22 meshes with the gear on the drum assembly to receive power and transmit the power to the remaining gears. Specifically, when the developing cartridge 1 is installed on the drum assembly, the developing gear 22 meshes with the photosensitive drum gear on the drum assembly, so that when the photosensitive drum rotates, the developing gear 22 is driven to rotate by the photosensitive drum gear, and the power is transmitted to the developing cartridge 1. The powder feeding gear 23 and the stirring gear 24 are directly or indirectly meshed with the developing gear 22 to realize the transmission of power to each component on the developing cartridge 1. This embodiment can enable the image forming apparatus to not require a dedicated power output member for the developing cartridge 1, and can reduce costs.

[0272] In some other embodiments, a plate member that swings or moves in the first direction can be used as a transmission member to transmit power from the first end 11 to the second end 12 to move the detected member 4, or the plate member and the detected member 4 can be integrally formed.

[0273] Embodiment 2:

[0274] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment 1.

[0275] As Figure 12 shown, the difference between this embodiment and Embodiment 1 is that the second tooth part 312a is provided as a plurality of cylindrical pin teeth, and the plurality of cylindrical pin teeth are arranged in sequence in the rotation direction of the first rotating member 31a, and the cylindrical pin teeth extend in the radial direction of the first rotating member 31a away from the rotation axis of the first rotating member 31a.

[0276] The third tooth part 321a is correspondingly provided as a plurality of cylindrical pin teeth, and the plurality of cylindrical pin teeth are arranged in sequence in the rotation direction of the second rotating member 32a, and the cylindrical pin teeth extend in the radial direction of the second rotating member 32a away from the rotation axis of the second rotating member 32a. The toothless part is provided on the third tooth part 321a, or can also be provided on the second tooth part 312a.

[0277] The third tooth part 321a engages with the second tooth part 312a (cylindrical pin tooth engagement) so that the first rotating part 31a drives the second rotating part 32a to rotate. The fourth tooth part 322a of the second rotating part 32a engages with the third rotating part 33a.

[0278] In this embodiment, the fourth rotating part is also cancelled. The number of the third rotating parts 33a is eight. The eight third rotating parts 33a are engaged in sequence, and the last third rotating part 33a (the one farthest from the first rotating part 31a) is directly engaged with the transmission rotating part 35a to transmit power to the transmission rotating part 35a.

[0279] In this embodiment, the triggering part 41a is directly arranged on the transmission rotating part 35a, that is, the transmission rotating part 35a can be regarded as the detected part. Four triggering parts 41a are arranged on the transmission rotating part 35a at intervals in the circumferential direction. The triggering part 41a is a protruding structure and is formed by extending along the radial direction of the transmission rotating part 35a away from the rotation axis of the transmission rotating part 35a. The number of the triggering parts 41a is set according to actual needs. The central angles corresponding to the multiple triggering parts 41a can be the same or different, so that the time for the triggering part 41a to maintain in the detection position is different to adapt to the identification of different types of developing cartridges 1.

[0280] Embodiment Three:

[0281] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment Two.

[0282] As Figure 13 and Figure 14 shown, the difference between this embodiment and Embodiment Two is that: only one triggering part 41c is arranged on the transmission rotating part 35c (the detected part); a driving protrusion is arranged on the first rotating part 31c and extends along the radial direction of the first rotating part 31c away from the axis of the first rotating part 31c. The driving protrusion includes a first driving protrusion 312c, a second driving protrusion 313c, and a third driving protrusion 314c which are arranged at intervals in sequence along the rotation direction of the first rotating part 31c. The first rotating part 31c only includes a first tooth part 311c for receiving the power of the driving component, and the second tooth part is cancelled. The third tooth part is cancelled on the second rotating part 32c, that is, the two are not engaged in a gear manner. A driven part 321c (i.e., a protruding structure) which extends along the radial direction of the second rotating part 32c away from the rotation axis of the second rotating part 32c is arranged on the second rotating part 32c. The driven part 321c is located on the movement tracks of the first driving protrusion 312c, the second driving protrusion 313c, and the third driving protrusion 314c. In this embodiment, there are 10 rotating parts whose rotation axes intersect with the first direction.

[0283] Wherein, the length (arc length) of the first driving protrusion 312c in the circumferential direction (i.e., the rotation direction) of the first rotating member 31c is greater than that of the second driving protrusion 313c and the third driving protrusion 314c.

[0284] A reset elastic member (not shown) is provided between the transmission rotating member 35c and the cartridge body 10. In this embodiment, the reset elastic member is a torsion spring. One end of the torsion spring abuts against the transmission rotating member 35c, and the other end abuts against the cartridge body 10.

[0285] When the first driving protrusion 312c, the second driving protrusion 313c, and the third driving protrusion 314c sequentially pass through the driven portion 321c, a force is applied to the driven portion 321c, causing the second rotating member 32c to rotate. The second rotating member 32c transmits the power to the fifth transmission gear 35c through the third rotating member 33c, causing the triggering portion 41c to rotate from the non-detection position to the detection position along with the fifth transmission gear 35c.

[0286] When the intervals between the first driving protrusion 312c, the second driving protrusion 313c, and the third driving protrusion 314c move to the driven portion 321c, under the action of the reset elastic member, the transmission rotating member 35c rotates clockwise and reverses by a certain angle, causing the triggering portion 41c to move from the detection position to the non-detection position. Thus, the third rotating member 33c and the second rotating member 32c also reverse by a certain angle, causing the driven portion 321c to return to a position where it can be touched by the first driving protrusion 312c, the second driving protrusion 313c, and the third driving protrusion 314c for the next touch.

[0287] Embodiment 4:

[0288] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment 1.

[0289] As Figures 15 to 23 shown, the difference between this embodiment and Embodiment 1 is that the fourth rotating member is cancelled, and the structures of the transmission rotating member and the detected member are different.

[0290] As Figure 17As shown, in this embodiment, the box body 10 is provided with a first support column 101, a second support column 102, a third support column 103, a fourth support column 104 and a fifth support column 105. The first support column 101 and the second support column 102 are located at the first end 11 and extend along the first direction. The third support column 103, the fourth support column 105 and the fifth support column 105 extend along the third direction. The third support column 103 is arranged close to the first end 11, and the fifth support column 105 is arranged close to the second end 12. In this embodiment, the fourth support column 104 is provided in multiple numbers, and the multiple fourth support columns 104 are arranged in the first direction. The box body 10 is provided with a mounting groove that is recessed along the third direction and extends along the first direction. The multiple fourth support columns 104 are located in the mounting groove. In this embodiment, the number of the fourth support columns 104 is preferably 13, and in other embodiments, the number of the fourth support columns 104 can be set according to actual needs. In this embodiment, the above support columns are preferably cylindrical.

[0291] As Figures 15 to 19 shown, the driving part 21 is located at the first end 11. The driving part 21 is rotatably supported by the first support column 101, and the rotation axis of the driving part 21 extends in the first direction. The first rotating member 31d is rotatably supported by the second support column 102, and the rotation axis of the first rotating member 31d extends in the first direction. The second rotating member 32d is rotatably supported by the third support column 103, and the rotation axis of the second rotating member 32d extends in the third direction. The third rotating member 33d is rotatably supported by the fourth support column 104. The third rotating member 33d is provided in multiple numbers and is arranged in the first direction. The multiple third rotating members 33d are engaged with each other. The number of the third rotating members 33d matches the number of the fourth support columns 104. In this embodiment, it is preferably provided with 13 third rotating members 33d. Along the first direction, with the direction from the first end 11 to the second end 12 as the indication direction, the third rotating member 33d closest to the first end 11 is the initial third rotating member 33d1, and the third rotating member 33d closest to the second end 12 is the final third rotating member 33dn. The initial third rotating member 33d1 is engaged with the second rotating member 32d to receive power and rotate, and drive each third rotating member 33d to rotate. That is, the fourth tooth part 322d of the second rotating member 32d is engaged with the fifth tooth part of the initial third rotating member 33d1, and the diameter of the fifth tooth part is greater than the diameter of the fourth tooth part. In this embodiment, the diameter of the third tooth part 321d of the second rotating member 32d is greater than the diameter of the fourth tooth part 322d. In the third direction, the third tooth part 321d is at least partially located between the outer surfaces of the fourth tooth part 322d and the fifth end 15.

[0292] As Figure 16 and Figure 20As shown, the developing cartridge 1 further includes a driving rotating member 35d. The driving rotating member 35d is disposed near the second end 12 and is rotatably supported by the fifth support post 105. The driving rotating member 35d includes a driving tooth portion 351d and a driving protrusion 352d. The driving tooth portion 351d meshes with the third last rotating member 33dn to receive power and cause the driving rotating member 35d to rotate. The driving protrusion 351d is disposed on the lower surface of the driving rotating member 35d and protrudes downward in the third direction. The driving protrusion 351d is disposed near the circumferential edge of the driving rotating member 35d. The driving protrusion 352d has an abutting surface, which is an inclined surface, a curved surface or a straight surface. The abutting surface is used to abut against the detected member 4d to drive the detected member 4d. In this embodiment, it is preferably that the extending direction of the abutting surface intersects with the third direction. That is, in this embodiment, there are 15 rotating members whose rotation axes intersect with the first direction.

[0293] As Figures 20 to 22 shown, the detected member 4d is located at the second end 12 and is used to trigger the detecting member. The detected member 4d includes a triggering portion 41d, a driven member 42d and a supported portion 43d. In the first direction, the supported portion 43d is located between the driven member 42d and the triggering portion 41d. The driven member 42d is used to receive the power that causes the detected member 4d to move. In this embodiment, the driven member 42d is preferably an inclined surface (the inclined surface includes a curved surface and a straight surface). The driven member 42d is abutted by the driving protrusion 352d of the driving rotating member 35d to cause the detected member 4d to swing. The extending direction of the swing axis of the detected member 4d intersects with the first direction. Preferably, the swing axis extends in the second direction. The supported portion 43d is the rotation center of the swing of the detected member 4d. The supported portion 43d is cylindrical and extends in the second direction. A first clamping portion 1212 is provided on the second cover 121. The first clamping portion 1212 is semi-circular or full-circular. In this embodiment, it is preferably semi-circular. The supported portion 43d is rotatably supported by the first clamping portion 1212 so that the detected member 4d is movably mounted on the second cover 121. In some embodiments, the detected member 4d is movably supported by the cartridge body 10. The triggering portion 41d is used to directly contact the detecting member. The detecting member is triggered during the upward swing of the triggering portion 41d.

[0294] As Figure 22 shown, a placing portion 1213 is provided on the second cover 121. A reset elastic member 36d is placed on the placing portion 1213. The reset elastic member 36d is an elastic member such as a sponge or a compression spring. In this embodiment, it is preferably a sponge. When the detected member 4d swings, the reset elastic member 36d is compressed and stores elastic potential energy. After the driven member 42d is disengaged from the abutment of the driving protrusion 352d, the detected member 4d swings in the reverse direction under the elastic action of the reset elastic member 36d to reset.

[0295] When the detected part 4d needs to trigger the detection part multiple times, the driving protrusion 352d on the driving rotating part 35d can abut against the detected part 4d multiple times, or multiple driving protrusions 352d can be provided on the driving rotating part 35d.

[0296] In order to prevent the detected part from swinging after the detection is completed, the driving tooth part 351d of the driving rotating part 35d can be set as a missing tooth part to disconnect the engagement with the third rotating part 33d, or the third rotating part 33d, the second rotating part 32d, or the first rotating part 31d can be provided with a missing tooth part to disconnect the transmission.

[0297] In this embodiment, the detected part 4d is made of a conductive material such as resin. The detected part 4d can be used as an electrode to receive the voltage output by the image forming apparatus. A conductive member is provided between the detected part 4d and the developing roller 131. The conductive member is electrically connected to the detected part 4d and the developing roller 131 so that the detected part 4d transfers the voltage to the developing roller 131. In this embodiment, the conductive member is preferably a steel sheet.

[0298] As Figure 21 shown, a locked part 1211 is further provided on the second cover 121. The locked part 1211 is used to prevent the developing cartridge 1 from detaching.

[0299] As Figure 21 shown, a powder filling port and a sealing cover 123 overlapping the powder filling port in the first direction are further provided at the second end 12. In the second direction, the powder filling port is located behind the detected part 4d. The developer is filled into the cartridge body 10 through the powder filling port. The sealing cover 123 is used to seal the powder filling port to prevent the developer from leaking.

[0300] As Figure 16 shown, in this embodiment, a cover member 150 is detachably and fixedly installed on the fifth end 15. The cover member 150 is installed on the cartridge body 10 by means of buckling and screw fixation, etc. The cover member 150 covers at least the transmission assembly part, playing a role in preventing the transmission assembly from falling off and protecting it. In some embodiments, the support column for rotatably supporting the rotating part whose rotation axis extends in the third direction can be provided on the cover member 150 so that the cover member 150 can at least rotatably support part of the transmission assembly.

[0301] Embodiment Five:

[0302] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment One.

[0303] As Figures 23 to 30 shown, the difference between this embodiment and Embodiment One lies in the different structure of the detected part.

[0304] As Figures 23 to 30As shown, in this embodiment, the toothless portion 343e is provided on the sixth tooth portion 341e of the fourth rotating member 34e. The box body 10 is provided with a first pivot shaft 152e and a second pivot shaft 153e extending upward in the third direction. The detected members include a first detected member 41e and a second detected member 42e. The first detected member 41e and the second detected member 42e are respectively rotatably mounted on the first pivot shaft 152e and the second pivot shaft 153e on the fifth end 15 around a rotation axis parallel to the third direction. The first detected member 41e includes a first driven member 412e and a first trigger portion 411e. The second detected member 42e includes a second driven member 422e and a second trigger portion 421e. The first driven member 412e is located on the right side of the first pivot shaft 152e, the first trigger portion 411e is located on the left side of the first pivot shaft 152e, the second driven member 422e is located on the right side of the second pivot shaft 153e, and the second trigger portion 421e is located on the left side of the second pivot shaft 153e. The first trigger portion 411e and the second trigger portion 421e are used to trigger the detection member. The first trigger portion 411e and the second trigger portion 421e extend leftward beyond the fifth end 15, that is, the first trigger portion 411e and the second trigger portion 421e are located at the second end 12. The first driven portion 4121e and the fourth driven portion 4122e are provided on the first driven member 412e, and the second driven portion 4221e and the third driven portion 4222e are provided on the second driven member 422e.

[0305] The first driven portion 4121e, the second driven portion 4221e, the third driven portion 4222e, and the fourth driven portion 4122e are the same as those described in the first embodiment, except that they are respectively provided on the first detected member 41e and the second detected member 42e.

[0306] As Figures 23 to 25As shown, a first abutting portion 413e is fixedly provided on the first detected member 41e, and a second abutting portion 151e is fixedly provided on the fifth end 15 of the box body 101. A first reset elastic member 43e is installed between the first abutting portion 413e and the second abutting portion 151e. In this embodiment, the first reset elastic member 43e is a torsion spring. The first reset elastic member 43e is sleeved on the first pivot shaft 152e. One end of the first reset elastic member 43e abuts on the first abutting portion 413e, and the other end abuts on the second abutting portion 151e. In this embodiment, the second reset elastic member 44e is a compression spring. One end of the second reset elastic member 44e abuts on the third abutting portion 423e fixed on the second detected member 42e, and the other end of the second reset elastic member 44e abuts on the fourth abutting portion 154e fixed on the fifth end 15 of the box body 101. The third abutting portion 423e and the fourth abutting portion 154e are arranged opposite to each other. The first reset elastic member 43e is used to keep the first detected member 41e in the non-detection position, and the second reset elastic member 44e is used to keep the second detected member 42e in the non-detection position.

[0307] The working process is as follows:

[0308] As Figure 26 shown, the fourth rotating member 34e starts to rotate. In the initial state, the sixth tooth portion 341e of the fourth rotating member 34e is in an engaged state with the fifth tooth portion of the third rotating member 33e. When the third rotating member 33e receives the power transmitted by the driving portion 21 and rotates, the third rotating member 33e drives the fourth rotating member 34e to rotate counterclockwise (observed from top to bottom). The fourth rotating member 34e then drives the transmission rotating member 35e to rotate clockwise through the engagement of the seventh tooth portion 342e and the transmission tooth portion.

[0309] As Figures 27 to 30 shown, in the initial state, the transmission protrusion 352e is located inside the first driven portion 4121e and keeps abutting on the first driven portion 4121e, that is, the first detected member 41e is in the detection position in the initial state. As the transmission protrusion 352e rotates, the transmission protrusion 352e leaves the first driven portion 4121e and disengages from the first driven portion 4121e. Under the action of the first reset elastic member 43e, the first detected member 41e swings clockwise by a certain angle from the detection position and rotates to the non-detection position.

[0310] Then the transmission protrusion 352e contacts the second driven portion 4221e and the third driven portion 4222e on the second detected member 42e in sequence, so that the second detected member 42e rotates counterclockwise by a certain angle from the non-detection position to the detection position twice at the first speed V1, and the second triggering portion 421e touches and triggers the detector twice at the first speed V1.

[0311] AsFigure 30 As shown, the rear drive projection 352e then contacts the fourth driven part 4122e on the first detected part 41e, causing the first detected part 41e to rotate counterclockwise from the non-detection position by a certain angle at the second speed V2 to move to the detection position, so that the second trigger part 421e on the second detected part 42e touches and triggers the detector at the second speed V2. The second speed V2 is greater than the first speed V1, and further enables the image forming apparatus to determine the information of the developing cartridge 1 according to the different touch speeds.

[0312] When the fourth rotating part 34e disconnects from the third rotating part 33e and stops moving, the first detected part 41e and the second detected part 42e also stop moving, completing the detection process.

[0313] Embodiment Six:

[0314] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment One.

[0315] As Figures 31 to 44 shown, the difference between this embodiment and Embodiment One is that in this embodiment, the idler gear includes a first idler gear 25f and a second idler gear 26f. The first idler gear 25f and the second idler gear 26f are rotatably installed at the first end 11 and the rotation axes extend in the first direction. The first idler gear 25f meshes with the driving gear 212 and meshes with the stirring gear 24f, and the second idler gear 26f meshes with the first idler gear 25f.

[0316] As Figure 32 shown, the transmission assembly further includes a sixth rotating part 36f, and the sixth rotating part 36f is a sixth transmission gear. A first support shaft 241f is coaxially and fixedly arranged on the stirring gear 24f. The sixth rotating part 36f is supported by the first support shaft 241f and can rotate relative to the first support shaft 241f, that is, the rotation of the stirring gear 24f does not drive the sixth rotating part 36f to rotate. The rotation axis of the sixth rotating part 36f extends in the first direction. The sixth rotating part 36f includes a ninth tooth part 361f and a tenth tooth part 362f that are coaxially and fixedly arranged. In the first direction, the ninth tooth part 361f is located on the left side of the tenth tooth part 362f, and the radius of the ninth tooth part 361f is greater than the radius of the tenth tooth part 362f. The ninth tooth part 361f meshes with the second idler gear 26f, and the tenth tooth part 362f meshes with the first tooth part of the first rotating part 31f, so that the rotation direction of the stirring gear 24f is opposite to the rotation direction of the sixth rotating part 36f. However, since the sixth rotating part 36f can rotate relative to the first support shaft 241f, the rotation between the sixth rotating part 36f and the stirring gear 24f does not affect each other.

[0317] As Figure 33 and Figure 34As shown, a second protective cover 121f is fixedly installed at the second end 12. A first track 1211f and a second track 1212f are provided on the second protective cover 121f. The first track 1211f and the second track 1212f extend in the second direction. A first detected part 41f and a second detected part 42f are respectively installed in the first track 1211f and the second track 1212f. The first detected part 41f is supported by the first track 1211f and can linearly slide relative to the box body 10 along the first track 1211f in the second direction. The second detected part 42f is supported by the second track 1212f and can linearly slide relative to the box body 10 along the second track 1212f in the second direction.

[0318] The first track 1211f is located above the second track 1212f. Correspondingly, the first detected part 41f is also located above the second detected part 42f.

[0319] As Figures 36 to 39 shown, the first detected part 41f includes a first sliding part 413f, a first triggering part 411f, and a first driven part 412f. Among them, the first sliding part 413f is slidably installed in the first track 1211f. The first triggering part 411f extends leftward from the left end of the first sliding part 413f and extends out of the first track 1211f. A first groove 12112f for the first triggering part 411f to extend out is formed on the left wall of the first track 1211f. The first groove 12112f extends in the second direction. The first driven part 412f extends rightward from the right end of the first sliding part 413f and extends out of the first track 1211f. A second groove 12111f for the first driven part 412f to extend out is formed on the right wall of the first track 1211f. The second groove 12111f extends in the second direction. To facilitate the installation of the first detected part 41f into the first track 1211f, the front ends of the first track 1211f, the first groove 12112f, and the second groove 12111f are all open, so that the first detected part 41f can be installed into the first track 1211f from the front ends of the first track 1211f, the first groove 12112f, and the second groove 12111f backward. A third connecting part 414f is fixedly provided on the first sliding part 413f. A fourth connecting part 12113f is fixedly provided on the left wall of the first track 1211f. Both the third connecting part 414f and the fourth connecting part 12113f are cylindrical. A first reset elastic part 45f is installed between the third connecting part 414f and the fourth connecting part 12113f. In this embodiment, the first reset elastic part 45f is a tension spring. The front end of the first reset elastic part 45f is fixedly connected to the third connecting part 414f, and the rear end of the first reset elastic part 45f is fixedly connected to the fourth connecting part 12113f. The first reset elastic part 45f is used to keep the first detected part 41f in the non-detection position or have a tendency to move towards the non-detection position.

[0320] As shown Figures 36 to 39 in the figure, the second detected part 42f includes a second sliding part 423f and a second triggering part 421f. The second sliding part 423f is slidably installed in the second track 1212f. The second triggering part 421f extends leftward from the left end of the second sliding part 423f and protrudes out of the second track 1212f. A third groove 12122f for the second triggering part 421f to protrude is formed on the left wall of the second track 1212f, and the third groove 12122f extends in the second direction. To facilitate the installation of the second detected part 42f into the second track 1212f, both the front ends of the second track 1212f and the third groove 12122f are open, so that the second detected part 42f can be installed into the second track 1212f from the front ends of the second track 1212f and the third groove 12122f backward. A first elastic member 46f is arranged between the rear end of the second detected part 42f and the rear wall of the second track 1212f. In this embodiment, the first elastic member 46f is a compression spring. The front end of the first elastic member 46f abuts against the rear end of the second sliding part 423f, and the rear end of the first elastic member 46f abuts against the rear wall of the second track 1212f. The first elastic member 46f is used to keep the second detected part 42f in the detection position or have a tendency to move toward the detection position. A first abutting part 422f is further arranged at the right end of the second sliding part 423f, and the first abutting part 422f extends rightward from the right end of the second sliding part 423f. A first hole 12121f is formed on the right wall of the second track 1212f.

[0321] As shown Figures 36 to 39As shown, a first pivot shaft 1213f extending in the third direction is provided on the second cover 121f. A trigger member 43f pivotable about the first pivot shaft 1213f is mounted on the first pivot shaft 1213f. The rotation axis of the trigger member 43f extends in the third direction. The trigger member 43f includes a pivoting portion, a first arm 431f, and a second arm 432f. The pivoting portion is rotatably mounted on the first pivot shaft 1213f. The pivoting portion can be set to a disc shape or a square shape. In this embodiment, the pivoting portion is generally square. The first arm 431f extends leftward from the pivoting portion, and the second arm 432f extends rightward from the pivoting portion. The first arm 431f is located on the left side of the first pivot shaft 1213f, and the second arm 432f is located on the right side of the first pivot shaft 1213f. The trigger member 43f can move between a triggered position and a non-triggered position. When the trigger member 43f is in the triggered position, the second detected member 42f is not limited by the trigger member 43f in the forward movement direction, so that the second detected member 42f can move forward to the detection position under the elastic force of the first elastic member 46f. When the trigger member 43f is in the non-triggered position, the first arm 431f passes through the first hole 12121f and extends into the second track 1212f to abut against the front end of the first abutting portion 422f. At the same time, the first arm 431f can also abut against the front wall of the first hole 12121f, so that the second detected member 42f is limited by the first arm 431f in the non-detection position. At the same time, the first arm 431f is restricted by the first hole 12121f and cannot swing forward, thereby ensuring that the second detected member 42f can be kept in the non-detection position, and the first elastic member 46f is in a state of generating elastic deformation and storing elastic potential energy.

[0322] As Figure 37 shown, a second elastic member 44f is also sleeved on the first pivot shaft 1213f. The second elastic member 44f is a torsion spring. A second abutting portion 1214f is fixedly provided on the second cover 121f. A third abutting portion 433f is fixedly provided on the trigger member 43f. One end of the second elastic member 44f abuts against the second abutting portion 1214f, and the other end abuts against the third abutting portion 433f. The second elastic member 44f is used to keep the trigger member 43f in the non-triggered position or have a tendency to move toward the non-triggered position.

[0323] As Figure 34 and Figure 35As shown in the figure, in this embodiment, a first driving protrusion 351f, a second driving protrusion 352f, a third driving protrusion 353f, and a fourth driving protrusion 354f that move together with the driving rotating member 35f are fixedly arranged on the driving rotating member 35f. The distances between the first driving protrusion 351f, the second driving protrusion 352f, the third driving protrusion 353f and the fifth end 15 in the third direction are a first distance, and the distance between the fourth driving protrusion 354f and the fifth end 15 in the third direction is a second distance. The first distance is greater than the second distance, that is, the first driving protrusion 351f, the second driving protrusion 352f, and the third driving protrusion 353f are located above the fourth driving protrusion 354f, so that the first driven part 412f of the first detected part 41f is located on the moving paths of the first driving protrusion 351f, the second driving protrusion 352f, and the third driving protrusion 353f, and the second arm 432f of the trigger member 43f is located on the moving path of the fourth driving protrusion 354f. The first driving protrusion 351f, the second driving protrusion 352f, the third driving protrusion 353f, and the fourth driving protrusion 354f are arranged in sequence from upstream to downstream in the rotation direction of the driving rotating member 35f.

[0324] The first driven part 412f of the first detected part 41f can be driven by being sequentially contacted by the first driving protrusion 351f, the second driving protrusion 352f, and the third driving protrusion 353f, so that the first detected part 41f moves from the non-detection position to the detection position.

[0325] The second arm 432f of the trigger member 43f can be driven by contacting the fourth driving protrusion 354f, so that the trigger member 43f swings clockwise from the non-trigger position to the trigger position.

[0326] In this embodiment, no toothless part is provided on the first rotating member 31f, and a toothless part 356f is provided on the driving tooth part 355f of the driving rotating member 35f.

[0327] As Figures 40 to 44 shown, the specific working process is as follows: The driving part 21 receives the power provided by the image forming apparatus and rotates clockwise (observed from right to left), and transmits the power to the driving rotating member 35f through the driving assembly and the transmission assembly. In the initial state, the driving tooth part 355f is in an engaged state with the seventh tooth part of the fourth rotating member 34, so that the driving rotating member 35f rotates counterclockwise (observed from top to bottom).

[0328] As Figures 40 to 42As shown, the rotation of the transmission rotating member 35f causes the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f to come into contact with the first driven portion 412f in sequence, thereby driving the first detected member 41f to slide forward from the non-detection position to the detection position along the first track 1211f at the first speed, thus triggering the detection member, causing the image forming apparatus to generate an electrical signal, and at the same time causing the first return elastic member 45f to be stretched and elastically deformed. As the transmission rotating member 35f rotates, when the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f are disengaged from the first driven portion 412f, under the elastic force of the first return elastic member 45f, the first detected member 41f moves backward from the detection position to the non-detection position along the first track 1211f. Thus, the first detected member 41f is successively touched and driven by the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f, and the first detected member 41f moves forward from the non-detection position to the detection position three times at the first speed along the first track 1211f, causing the image forming apparatus to generate electrical signals three times. And since the rotation speed of the transmission rotating member 35f remains unchanged, the linear velocities of the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f are the same, so that the moving speed of the first detected member 41f is the first speed during the process of being driven by the first transmission protrusion 351f, the second transmission protrusion 352f, and the third transmission protrusion 353f to move from the non-detection position to the detection position multiple times. In other embodiments, the number of transmission protrusions can be increased or decreased to increase or decrease the number of times the first driven portion 412f is driven, so that the image forming apparatus can generate more or fewer electrical signals to distinguish different model specifications of the developing cartridge 1.

[0329] As Figure 43 and Figure 44As shown, in the initial state, the first elastic member 46f is in an elastically deformed state. After the first driving protrusion 351f, the second driving protrusion 352f, and the third driving protrusion 353f all come into contact with the first driven portion 412f, the fourth driving protrusion 354f comes into contact with the second arm 432f of the actuating member 43f and drives the actuating member 43f to swing clockwise by a certain angle from the non-actuated position to the actuated position, causing the first arm 431f of the actuating member 43f to swing clockwise by a certain angle, such that the first arm 431f disengages from the first abutting portion 422f, thereby no longer limiting the second detected member 42f. At this time, under the elastic force of the first elastic member 46f, the second detected member 42f moves forward along the second track 1212f from the non-detection position to the detection position at a second speed, thereby driving and triggering the detection member in the image forming apparatus for the fourth time, and the second speed is greater than the first speed, so that the image forming apparatus can generate different electrical signals according to the different triggering speeds, and further distinguish information such as the model specifications of different developing cartridges 1. In other embodiments, first elastic members 46f of different specifications can be selected to increase or decrease the second speed.

[0330] In this embodiment, the first length of the first driving protrusion 351f in the circumferential direction is greater than the second lengths of the second driving protrusion 352f and the third driving protrusion 353f in the circumferential direction, so that the time for which the first detected member 41f remains in the detection position when the first driving protrusion 351f contacts the first driven portion 412f is longer than the time for which the first triggering portion 411f remains in the detection position when the second driving protrusion 352f or the third driving protrusion 353f contacts the first driven portion 412f. Thus, the image forming apparatus can distinguish different model specifications of the developing cartridge 1 according to the time for which the first detected member 41f remains in the detection position each time it triggers the detection member.

[0331] Embodiment Seven:

[0332] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment Six.

[0333] Such as Figure 45 and Figure 46As shown, the difference between this embodiment and the sixth embodiment is that the transmission assembly further includes a seventh rotating member 37g and an eighth rotating member 38g. The seventh rotating member 37g is a seventh transmission gear, and the eighth rotating member 38g is an eighth transmission gear. The seventh rotating member 37g and the eighth rotating member 38g are coaxially arranged, with the seventh rotating member 37g located above the eighth rotating member 38g. The seventh rotating member 37g and the eighth rotating member 38g are rotatably arranged on the fifth end 15 of the box body 101, and the rotation axis is parallel to the third direction. The seventh rotating member 37g and the eighth rotating member 38g are located between the first third rotating member 331g and the second third rotating member 332g from right to left. The seventh rotating member 37g meshes with the first third rotating member 331g, and the eighth rotating member 38g meshes with the second third rotating member 332g. In this embodiment, the number of the third transmission gears is reduced by one, and the reduced third rotating member 33 is replaced by the seventh rotating member 37g and the eighth rotating member 38g.

[0334] As Figure 45 and Figure 46 shown, a first delay protrusion 371g is provided at the lower end of the seventh rotating member 37g, and a second delay protrusion 381g is provided at the upper end of the eighth rotating member 38g. In this embodiment, the number of both the first delay protrusion 371g and the second delay protrusion 381g is two. The first delay protrusion 371g is symmetrically arranged about the rotation axis of the seventh rotating member 37g, and the second delay protrusion 381g is symmetrically arranged about the rotation axis of the eighth rotating member 38g. In the initial state, the first delay protrusion 371g and the second delay protrusion 381g do not contact. When the driving part 21 receives power and rotates, the first rotating member is driven to rotate through the driving assembly. The first rotating member drives the second rotating member 32 to rotate. The second rotating member 32 drives the first third rotating member 331g to rotate. The first third rotating member 331g then drives the seventh rotating member 37g to rotate, so that the first delay protrusion 371g on the seventh rotating member 37g rotates from a position where it does not contact the second delay protrusion 381g to a position where it contacts the first delay protrusion 371g. Then, the power of the seventh rotating member 37g is transmitted to the eighth rotating member 38g through the contact between the first delay protrusion 371g and the second delay protrusion 381g. The eighth rotating member 38g then transmits the power to the second third rotating member 332g, and finally the power is transmitted to the first detected part 41f and the second detected part through the transmission assembly to realize the detection process.

[0335] In some embodiments, the seventh rotating member 37g and the eighth rotating member 38g can be arranged between any two engaged third rotating members 33.

[0336] With the above design, when the driving part 21 rotates by receiving the power output from the image forming apparatus, the transmission rotating member 35f will not rotate synchronously with the rotation of the driving part 21. Thus, the contact time between the first transmission protrusion 351f and the first driven part 412f in the initial state is extended, that is, the duration for which the first detected member 41f is held at the detection position under the action of the first transmission protrusion 351f is extended, so that the length of the first transmission protrusion 351f in the circumferential direction in this embodiment can be set to be the same as the lengths of the second transmission protrusion 352f and the third transmission protrusion 353f in the circumferential direction.

[0337] Embodiment VIII:

[0338] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment I.

[0339] As Figures 47 to 55 shown, the difference between this embodiment and Embodiment I is that: the transmission assembly includes a first rotating member 31h, a second rotating member 32h, a transmission rotating member 35h, and a flexible member 36h.

[0340] As Figure 47 and Figure 48 shown, the second tooth part 312h is arranged as a cylindrical pin tooth distributed on the circumferential surface of the first rotating member 31h around the rotation direction of the first rotating member 31h, and the cylindrical pin tooth extends along the radial direction of the first rotating member 31h away from the rotation axis of the first rotating member 31h.

[0341] The third tooth part 321h is arranged as a cylindrical pin tooth shape distributed on the circumferential surface of the second rotating member 32h around the rotation direction of the second rotating member 32h, and a toothless part is arranged on the third tooth part 321h, and the third tooth part 321h engages with the second tooth part 312h.

[0342] A first pulley part 322h is provided on the second rotating member 32h to replace the fourth tooth part.

[0343] In this embodiment, the flexible member 36h moves by receiving the power from the first end 11. Specifically, the flexible member 36h transmits the power from the second rotating member 32h to the transmission rotating member 35h. The flexible member 36h is at least partially located between the first end 11 and the second end 12 and at least partially moves in the first direction. The flexible member 36h is preferably a transmission belt.

[0344] As Figure 48 shown, a second pulley part 351h is provided on the transmission rotating member 35h to replace the transmission tooth part. The flexible member 36h (transmission belt) is installed on the first pulley part 322h and the second pulley part 351h to form a belt transmission mechanism to achieve power transmission.

[0345] As Figure 48 andFigure 49 As shown, a contact member is also fixedly provided on the fifth end 15. The contact member includes a first contact protrusion 152h, a second contact protrusion 153h, a third contact protrusion 154h, and a delay protrusion 151h. The first contact protrusion 152h has a first inclined surface 1521h, the second contact protrusion 153h has a second inclined surface 1531h, and the third contact protrusion 154h has a third inclined surface 1541h. The first contact protrusion 152h, the second contact protrusion 153h, the third contact protrusion 154h, and the delay protrusion 151h are arranged in a ring, and there are intervals between the first contact protrusion 152h, the second contact protrusion 153h, and the third contact protrusion 154h in the circumferential direction. The delay protrusion 151h contacts the third contact protrusion 154h. The length of the delay protrusion 151h in the circumferential direction is greater than that of the first contact protrusion 152h, the second contact protrusion 153h, and the third contact protrusion 154h. The first inclined surface 1521h, the second inclined surface 1531h, and the third inclined surface 1541h all intersect with the second direction. The angle between the first inclined surface 1521h and the second direction is B1, the angle between the second inclined surface 1531h and the second direction is B2, and the angle between the third inclined surface 1541h and the second direction is B3, and B3 < B2, B1.

[0346] As Figure 50 shown, a first contact portion 354h for contacting the contact member is provided on the transmission rotating member 35h. When the transmission rotating member 35h receives the power transmitted by the flexible member 36h, the first contact portion 354h rotates following the transmission rotating member 35h. When the first contact portion 354h rotates, it contacts the contact member and is subjected to the acting force provided by the contact member and moves in the third direction.

[0347] As Figure 48 and Figure 50 shown, a rotating shaft protruding upward in the third direction is also fixedly provided on the fifth end 15. The transmission rotating member 35h rotates around the rotating shaft. An installation hole is coaxially provided on the rotating shaft, and a limiting member 39h is installed in the installation hole. As an embodiment, the limiting member 39h is connected to the installation hole by a threaded connection. A limiting portion 391h is provided at the upper end of the limiting member 39h. The limiting portion 391h is in a disc shape. An installation groove 353h is provided on the transmission rotating member 35h. The installation groove 353h is in a downwardly concave circular ring shape. A first elastic member 38h is provided in the installation groove 353h. The first elastic member 38h can be a compression spring. One end of the first elastic member 38h abuts against the limiting portion 391h and the other end abuts against the installation groove 353h. The first elastic member 38h is used to apply a downward force to the transmission rotating member 35h so that the first contact portion 354h keeps in close contact with the contact member.

[0348] As Figure 48As shown, drive ribs 352h are further provided on the outer circumferential surface of the drive rotating member 35h. The drive ribs 352h are annular and protrude in the radial direction away from the rotation axis of the drive rotating member 35h.

[0349] As Figure 48 and Figure 51 shown, a second protective cover 121 is detachably mounted on the second end 12. A guiding post 1211h is fixedly provided on the second protective cover 121. The guiding post 1211h extends upward along the third direction. A touching member 37h is slidably mounted on the guiding post 1211h. A sliding hole 373h is provided on the touching member 37h along the third direction. The sliding hole 373h is for the guiding post 1211h to be inserted and is slidably engaged with the guiding post 1211h. A chute 371h recessed leftward is provided at the right end of the touching member 37h. The chute 371h is slidably engaged with the drive ribs 352h, so that the touching member 37h can move up and down in the third direction together with the drive rotating member 35h. A first driving inclined surface 372h is provided on the touching member 37h. The first driving inclined surface 372h intersects with the third direction. The front end of the first driving inclined surface 372h is lower than the rear end.

[0350] As Figure 48 and Figure 51 shown, a first track 1212h for mounting the detected member 4h is further fixedly provided on the second protective cover 121. The detected member 4h is slidably mounted in the first track 1212h and can slide back and forth in the second direction along the first track 1212h. A second elastic member 43h is mounted between the rear end of the detected member 4h and the first track 1212h. The second elastic member 43h is used to make the detected member 4h have a tendency to slide forward. The second elastic member 43h is a compression spring. The front end of the second elastic member 43h abuts against the rear end of the detected member 4h. The rear end of the second elastic member 43h abuts against the rear end of the first track 1212h.

[0351] A second driving inclined surface 42h for contacting the first driving inclined surface 372h is provided on the detected member 4h. The second driving inclined surface 42h intersects with the third direction, and the front end of the second driving inclined surface 42h is lower than the rear end. The front end of the detected member 4h is a triggering portion 41h.

[0352] The specific detection process is as follows:

[0353] As Figures 52 to 55 shown, the first rotating member 31h transmits power to the second rotating member 32h through the engagement of the second tooth portion 312h and the third tooth portion 321h. The second rotating member 32h drives the flexible member 36h to move, and the flexible member 36h drives the drive rotating member 35h to rotate.

[0354] In the initial position, the first abutting portion 354h of the transmission rotating member 35h abuts against the upper end of the third delay protrusion 151h and is located at the upstream end of the third delay protrusion 151h in the rotation direction of the transmission rotating member 35h.

[0355] As the transmission rotating member 35h rotates, the first abutting portion 354h rotates along the third delay protrusion 151h. During this process, the actuator 37h is in the first position, the detected member 4h is in the detection position, and the triggering portion 41h touches the detector.

[0356] As the transmission rotating member 35h rotates, the first abutting portion 354h rotates to the interval between the third delay protrusion 151h and the first abutting protrusion 152h. Under the elastic force of the first elastic member 38h, the downward movement of the transmission rotating member 35h drives the actuator 37h to move downward from the first position to the second position, so that the first transmission inclined surface 372h applies a force to the second transmission inclined surface 42h, causing the detected member 4h to move backward against the elastic force of the second elastic member 43h, and thus moving from the detection position to the non-detection position.

[0357] As the transmission rotating member 35h rotates, the first abutting portion 354h rotates to the first abutting protrusion 152h and moves upward along the first inclined surface 1521h on the first abutting protrusion 152h, thereby driving the transmission rotating member 35h to move upward, so that the actuator 37h moves from the second position to the first position together with the transmission rotating member 35h, causing the first transmission inclined surface 372h to gradually disengage from the second transmission inclined surface 42h, and causing the detected member 4h to move from the non-detection position to the detection position under the elastic force of the second elastic member 43h.

[0358] As the transmission rotating member 35h rotates, the first abutting portion 354h rotates to the interval between the first abutting protrusion 152h and the second abutting protrusion 153h. Under the elastic force of the first elastic member 38h, the downward movement of the transmission rotating member 35h drives the actuator 37h to move downward from the first position to the second position, thereby causing the detected member 4h to move from the detection position to the non-detection position.

[0359] As the transmission rotating member 35h rotates, the first abutting portion 354h abuts against the second abutting protrusion 153h. The abutting and disengagement of the two are the same as those of the first abutting protrusion 152h, and will not be elaborated here.

[0360] As the driving rotating member 35h rotates, the first abutting portion 354h rotates to the third abutting protrusion 154h and moves upward along the third inclined surface 1541h on the third abutting protrusion 154h, thereby driving the driving rotating member 35h to move upward. As a result, the actuating member 37h moves from the second position to the first position together with the driving rotating member 35h, causing the first driving inclined surface 372h to gradually disengage from the second driving inclined surface 42h, and causing the detected member 4h to move from the non-detection position to the detection position under the elastic force of the second elastic member 43h. And because the angle between the third inclined surface 1541h and the second direction is smaller than the angles between the first inclined surface 1521h and the second direction and between the second inclined surface 1531h and the second direction, when the first abutting portion 354h moves upward along the third inclined surface 1541h, the moving speed V3 in the up-down direction is greater than the moving speeds V1 and V2 in the up-down direction when the first abutting portion 354h moves upward along the first inclined surface 1521h and the second inclined surface 1531h. As a result, the actuating member 37h moves upward at a speed of V3, and the detected member 4h also moves from the non-detection position to the detection position faster.

[0361] As the driving rotating member 35h rotates, the first abutting portion 354h rotates again to the upstream end of the third delay protrusion 151h in the rotation direction of the driving rotating member 35h. At the same time, the toothless portion of the second rotating member 32h rotates to a position opposite to the second tooth portion 312h, thereby stopping receiving power, causing the transmission assembly to have no power input, and the detected member 4h to stop moving, thus completing the detection process. That is, in this embodiment, the driving rotating member 35h serves as an intermediate member to enable the flexible member 36h to drive the detected member 4h to move.

[0362] Using the flexible member in this embodiment to replace the third rotating member and the fourth rotating member reduces the number of parts and the space occupancy rate, enabling the cartridge 10 to be designed larger and increasing the developer capacity.

[0363] Embodiment Nine:

[0364] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment Eight.

[0365] As Figure 56 shown, the difference between this embodiment and Embodiment Eight is that:

[0366] A cylindrical first connecting post 151i (driving rotating member) protruding upward is provided on the fifth end 15. The flexible member 36i is movably sleeved between the second rotating member 32i and the first connecting post 151i, and the first connecting post 151i can rotate or not rotate;

[0367] The flexible member 36i is successively provided with a first protrusion 361i, a second protrusion 362i, a third protrusion 363i, and a fourth protrusion 364i that are spaced apart from each other.

[0368] The length of the first protrusion 361i in the first direction is greater than the lengths of the second protrusion 362i, the third protrusion 363i, and the fourth protrusion 364i in the first direction.

[0369] A first inclined surface 3621i is provided on the second protrusion 362i, a second inclined surface 3631i is provided on the third protrusion 363i, and a third inclined surface 3641i is provided on the fourth protrusion 364i.

[0370] The first inclined surface 3621i, the second inclined surface 3631i, and the third inclined surface 3641i all intersect the first direction. And the included angle between the third inclined surface 3641i and the first direction is greater than the included angles between the second inclined surface 3631i and the third inclined surface 3641i and the first direction. The detected member is a swing rod structure, and its swing axis intersects the first direction. The driven member 42i of the detected member extends to the middle of the cartridge 10 in the first direction, and a driven protrusion 421i (equivalent to the first driven part, the second driven part, the third driven part, and the fourth driven part) is provided on the driven member 42i of the detected member. In this embodiment, another implementation manner of the return elastic member 1521i is provided. Specifically, the return elastic member 1521i is a compression spring. A groove 152i for installing the return elastic member 1521i is provided on the fifth end 15. The groove 152i is formed by being recessed downward. A return protrusion 423i protruding downward is provided on the driven member 42i. The return protrusion 423i is inserted into the groove 152i and can slide relative to the groove 152i. One end of the return elastic member 1521i abuts against the return protrusion 423i and the other end abuts against the rear end of the groove 152i.

[0371] As the flexible member 36i moves, the first protrusion 361i, the second protrusion 362i, the third protrusion 363i, and the fourth protrusion 364i move leftward in the first direction together with the flexible member 36i, and successively apply forces to the driven protrusion 421i, so that the driven protrusion 421i drives the detected member to move and the trigger portion 41i triggers the detection member. After any one of the first protrusion 361i, the second protrusion 362i, the third protrusion 363i, and the fourth protrusion 364i passes the driven protrusion 421i, the detected member can return from the detection position to the non-detection position under the elastic force of the return elastic member 1521i, so that the detection member can return from the triggered state to the untriggered state multiple times.

[0372] Embodiment Ten:

[0373] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment Eight.

[0374] like Figure 57 As shown, the difference between this embodiment and the eighth embodiment is that the transmission block, abutment member and other structures are eliminated.

[0375] In this embodiment, the transmission rotating member 35j is rotatably disposed on the second protective cover 121, the rotation axis of the transmission rotating member 35j is parallel to the third direction, and the transmission rotating member 35j, the second rotating member 32h and the flexible member 36h constitute a belt transmission system, that is, in this embodiment, the flexible member 36h extends from the first end 11 to the second end 12. The triggering portion 41j is fixedly disposed together with the transmission rotating member 35j and can rotate together with the transmission rotating member 35j to make a circular motion.

[0376] In this embodiment, the diameter of the transmission rotating member 35j is smaller than the diameter of the second rotating member 32h, and the transmission ratio between the second rotating member 32h and the transmission rotating member 35j is 1:4, so that the second rotating member 32j rotates one circle and the transmission rotating member 35j rotates four circles, thereby causing the triggering part 41j to move four times from a non-detection position that does not contact the detection member to a detection position that contacts the detection member, thereby completing four triggering of the detection member.

[0377] In some embodiments, the triggering part may also be arranged on the transmission rotating member, and the triggering part may be single or multiple.

[0378] Embodiment eleven:

[0379] If not otherwise specified, the structure of the developing box 1 in this embodiment is the same as that in the eighth embodiment.

[0380] like Figure 58 As shown, the detected member 4m is rotatably mounted on an upwardly protruding pivot column 1211m on the second protective cover 121, a lever 352m is fixedly provided on the transmission rotating member 35m and extends radially in a direction away from the rotation axis of the transmission rotating member 35m, and a driven groove 42m is provided on the driven member of the detected member 4m, and the lever 352m is inserted into the driven groove 42m. A reset elastic member 1212m is also installed on the second protective cover. The reset elastic member 1212m is sleeved on an upward protrusion provided on the second protective cover 121. One end of the reset elastic member 1212m abuts against the reset protrusion 353m on the circumferential surface of the transmission rotating member 35m, and the other end abuts against the first limiting protrusion 1213m protruding upward on the second protective cover 121 to limit the rotation of the reset elastic member 1212m. The reset elastic member 1212m is used to provide counterclockwise rotation force to the transmission rotating member 35m, and the flexible member 36h provides clockwise rotation force to the transmission rotating member 35m.

[0381] When the transmission rotating member 35m rotates following the movement of the flexible member 36h, the transmission rotating member 35m drives the detected member 4m to swing back and forth through the shifting rod 352m.

[0382] Example 12:

[0383] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Example 8.

[0384] The difference between this embodiment and Example 8 lies in the different structure of the transmission assembly. The transmission assembly includes a first rotating member 31n, a second rotating member 32n, a flexible member 36n, and a translational member 37n.

[0385] As Figures 59 - 61 shown, the second rotating member 32n is located at the first end 11. The second rotating member 32n includes a third tooth portion 321n (bevel gear) and a first winding portion 322n. The first winding portion 322n (equivalent to a fourth tooth portion). The third tooth portion 321n meshes with the second tooth portion 312n (bevel gear) of the first rotating member 31d so that the second rotating member 32n rotates following the first rotating member 31d. The third tooth portion 321n includes a tooth missing portion 3211n, and the tooth missing portion 3211n is used to disconnect the engagement with the first rotating member 31d, that is, to make the second rotating member 32n no longer rotate following the first rotating member 31d. The first winding portion 322n is preferably cylindrical. In some embodiments, the first winding portion 322n may also be other shapes such as a prism. A first connecting portion 3221n is provided on the first winding portion 322n, and the first connecting portion 3221n is in the shape of a hole.

[0386] As Figure 59 and Figure 60 shown, the flexible member 36n is movably installed on the cartridge body 10. The flexible member 36n extends in the first direction. The flexible member 36n at least partially moves linearly in the first direction. The flexible member 36n includes a first end portion 361n and a second end portion 362n in the first direction. The first end portion 361n is disposed near the first end 11, and the second end portion 362n is disposed near the second end 12. The first end portion 361n can be wound around the first winding portion 322n. First, the first end portion 361n is connected to the first connecting portion 3221n of the first winding portion 322n by means of bundling, welding, gluing, etc. to prevent the flexible member 36n from detaching from the second rotating member 32n, and then continuously winds around the first winding portion 322n during the rotation of the second rotating member 32n. The flexible member 36n has the characteristic of not being compressible or stretchable (not being compressible or stretchable includes being slightly compressed and stretched), that is, not being elastically deformable, but can be bent. The flexible member can be a common rope, or other components such as copper wire and steel wire, as long as it has the above characteristics. In this embodiment, the flexible member 36n is preferably a steel wire rope.

[0387] As Figure 60 and Figure 61As shown, the cartridge body 10 is provided with a mounting groove (not shown) that is recessed in the third direction and extends in the first direction. The translation member 37n is movably mounted in the mounting groove and can move in the first direction. The translation member 37n includes a driving protrusion 371n and a second connecting portion 372n. The second connecting portion 372n is used to fixedly connect with the second end portion 362n of the flexible member 36n by means such as bundling, welding, or gluing. The second connecting portion 372n is preferably extended in the first direction and has a groove recessed in the radial direction. The size of the second connecting portion 372n is set to match the size of the flexible member 36n. The translation member 37n can follow the movement of the flexible member 36n, specifically moving in the first direction towards the direction close to the first end 11 (moving to the right). The driving protrusion 371n is a protrusion extending in the third direction. In this embodiment, it is preferably extended downward along the third direction, and in other embodiments, it can be extended upward. The driving protrusion 371n is provided with an abutting surface, and the abutting surface is preferably an inclined surface, and can also be a curved surface or a straight surface.

[0388] As Figures 59 to 61 shown, the detected member 4n is swingably mounted on the second cover 121. The detected member 4n includes a driven member 42n, a supported portion 43n, and a triggering portion 41n. The driven member 42n is provided with a first driven portion 421n and a second driven portion 422n. In the first direction, the first driven portion 421n is farther from the first end 11 than the second driven portion 422n, and there is a gap between them in the first direction. The first driven portion 421n and the second driven portion 422n are protrusions extending upward in the third direction. Both of them are preferably provided with an abutted surface, and the abutted surface is preferably an inclined surface, and can also be a curved surface or a straight surface. The supported portion 43n is in a hole shape and is supported by the second cover 121. The supported portion 43n is the swing center of the detected member 4n. At the factory preset, the driving protrusion 371n is located on the left side of the first driven portion 421n.

[0389] As Figure 60 shown, the developing cartridge 1 further includes a reset elastic member 45n. In this embodiment, the reset elastic member 45n is preferably a compression spring, and can also be an elastic medium such as a sponge. The reset elastic member 45n is used to swing the detected member 4n in the reverse direction to reset (move from the detection position to the non-detection position).

[0390] As Figures 59 to 61As shown, when the driving component receives the power output by the image forming apparatus, the second rotating member 32n starts to rotate following the first rotating member 31d, and the first end portion 361n of the flexible member 36n is further wound around the first winding portion 322n, such that the flexible member 36n moves linearly in the first direction to the right and drags the translating member 37n to translate in the first direction towards the direction close to the first end 11 (move to the right). The driving protrusion 371n abuts against the first driven portion 421n of the detected member 4n, such that the detected member 4n swings, the triggering portion 41n swings upward to the detection position to trigger the detecting member, and the reset elastic member 45n is compressed. As the second rotating member 32n further rotates, more portions of the flexible member 36n are wound around the first winding portion, the translating member 37n moves further to the right, the driving protrusion 371n disengages from abutting against the first driven portion 421n, and the detected member 4n swings in the reverse direction under the elastic action of the reset elastic member 45n to reset to the non-detection position. After the translating member 37n continues to translate, it abuts against the second driven portion 422n such that the detected member 4n swings to the detection position again to trigger the detecting member again. After the second abutment, the detected member 4n disengages from abutting against the translating member 37n, the detected member 4d no longer swings after resetting, the toothless portion 3211n of the second rotating member 32n faces the second tooth portion 312n of the first rotating member 31n, the second rotating member 32n disengages from meshing with the first rotating member 31n, the second rotating member 32n stops rotating, and the flexible member 36n no longer moves in the first direction. In this embodiment, the diameter of the flexible member 36n is preferably not greater than 1 mm, and in other embodiments, it can be set according to actual requirements. In this embodiment, the number, size, and interval of the driven portions on the detected member can be set according to actual requirements. That is, in this embodiment, the translating member 37n is used as an intermediate member to enable the flexible member 36n to drive the detected member 4n to move.

[0391] It can be known that the length formed by the distance that the flexible member 36n moves in the first direction is the same as or similar to the length formed by the rotation of the third tooth portion 321n of the second rotating member 32n.

[0392] Embodiment Thirteen:

[0393] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment Twelve.

[0394] As Figure 62 and Figure 63 shown, the difference between this embodiment and Embodiment Twelve is that: the structure of the transmission component is different, and the transmission component includes a first rotating member, a second rotating member 32n, a transmission rotating member 35p, and a flexible member 36n.

[0395] As Figure 62 and Figure 63As shown, in this embodiment, the second rotating member 32n is not provided with a toothless portion, and the toothless portion is provided on the first tooth portion of the first rotating member. A first winding portion 322n that extends upward and is cylindrical is fixedly provided on the second rotating member 32n. First driving protrusions 351p, second driving protrusions 352p, and third driving protrusions 353p that move together with the driving rotating member 35p are provided at intervals in the circumferential direction on the driving rotating member 35p. A second winding portion 354p that extends upward and is cylindrical is fixedly provided on the driving rotating member 35p. A flexible member 36n is provided between the first winding portion 322n and the second winding portion 354p. The first end of the flexible member 36n is fixedly connected to the first winding portion 322n, and the second end is fixedly connected to the second winding portion 354p. In the initial state, the flexible member 36n is wound around the second winding portion 354p so that the flexible member 36n is in a taut state between the first winding portion 322n and the second winding portion 354p.

[0396] As Figure 63 shown, a 1211p extending in the first direction is provided on the second cover 121. The detected member 4p can slide along the first track 1211p and generate a displacement in the first direction relative to the box body 101. The detected member 4p includes a trigger portion 41p, a third sliding portion 43p, and a driven member 42p that are fixedly connected together in sequence from left to right. The third sliding portion 43p is installed in the first track 1211p and can slide in the first direction along the first track 1211p.

[0397] A second hole is formed in the left wall of the first track 1211p. The trigger portion 41p can extend leftward out of the second hole to touch the detection member. A detected inclined surface 411p is provided on the trigger portion 41p, and the inclination direction of the detected inclined surface 411p is set such that the left end is more backward than the right end.

[0398] The driven member 42p is touched and driven by the first driving protrusion 351p, the second driving protrusion, and the third driving protrusion 353p. A driven inclined surface 421p is provided on the driven member 42p, and the inclination direction of the driven inclined surface 421p intersects with the first direction and the second direction.

[0399] A first abutting portion 44p that extends upward is further provided at the upper end of the third sliding portion 43p. A reset elastic member is installed between the first abutting portion 44p and the left wall of the first track 1211p. The left end of the reset elastic member 45p abuts against the left wall of the first track 1211p, and the right end of the reset elastic member 45p abuts against the first abutting portion 44p. The reset elastic member is used to keep the detected member 4p in the non-detection position or have a tendency to move rightward to the non-detection position.

[0400] The second rotating member 32n is driven by the first rotating member to rotate, so that the first winding portion 322n pulls the flexible member 36n to move linearly in the first direction. Since the flexible member 36n is wound around the second winding portion 354p in the initial state, when the flexible member 36n is pulled, the second winding portion 354p drives the transmission rotating member 35p to rotate counterclockwise (viewed from top to bottom), and at the same time, the flexible member 36n is gradually wound onto the first winding portion 322n.

[0401] When the transmission rotating member 35p rotates, the first transmission protrusion 351p, the second transmission protrusion 352p, and the third transmission protrusion 353p sequentially touch the driven inclined surface 421p of the driven member 42p. Through the action of the driven inclined surface 421p, part of the acting force applied by the first transmission protrusion 351p, the second transmission protrusion 352p, and the third transmission protrusion 353p is converted into an acting force to the left in the first direction, so that the detected member 4p moves from the non-detection position to the detection position to the left, causing the detected inclined surface 411p to trigger the detection member, and at the same time, the first abutting portion 44p compresses the reset elastic member 45p. That is, in this embodiment, the transmission rotating member 35p serves as an intermediate member to drive the detected member 4h to move by the flexible member 36h.

[0402] When the driven member 42p is disengaged from the first transmission protrusion 351p, the second transmission protrusion 352p, and the third transmission protrusion 353p, under the elastic force of the reset elastic member 45p, the detected member 4p moves from the detection position to the non-detection position to the right, thereby stopping triggering the detection member.

[0403] Embodiment Fourteen:

[0404] Unless otherwise specified, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment Thirteen.

[0405] As Figure 64 and Figure 65 shown, the difference between this embodiment and Embodiment Thirteen is that the first transmission inclined surface 3511q, the second transmission inclined surface 3521q, and the third transmission inclined surface 3531q are further provided on the first transmission protrusion 351q, the second transmission protrusion 352q, and the third transmission protrusion 353q respectively. The first transmission inclined surface 3511q, the second transmission inclined surface 3521q, and the third transmission inclined surface 3531q all extend along the circumferential direction of the transmission rotating member 35q. In the rotation direction of the transmission rotating member 35q, the inclination directions of the first transmission inclined surface 3511q, the second transmission inclined surface 3521q, and the third transmission inclined surface 3531q are the same. Taking the inclination direction of the first transmission inclined surface 3511q as an example to illustrate the inclination direction, the inclination direction of the first transmission inclined surface 3511q is set such that the upstream end of the first transmission inclined surface 3511q is higher than the downstream end in the rotation direction of the transmission rotating member 35q.

[0406] AsFigure 64 As shown, in this embodiment, the first track 1211q extends in the third direction. The detected member 4q is slidably mounted in the first track 1211q and slides along the first track 1211q in the third direction and generates a displacement relative to the box body 101. The driven member 42q extends rightward out of the first track 1211q and is located on the moving paths of the first transmission inclined surface 3511q, the second transmission inclined surface 3521q, and the third transmission inclined surface 3531q. The triggering portion 41q extends leftward out of the first track 1211q.

[0407] When the flexible member 36q drives the transmission rotating member 35q to rotate, the first transmission inclined surface 3511q, the second transmission inclined surface 3521q, and the third transmission inclined surface 3531q rotate together with the transmission rotating member 35q and sequentially contact the driven member 42q of the detected member 4q, thereby providing a force with a component force in the upward direction to the driven member 42q, so that the detected member 4q moves upward from the non-detection position to the detection position and triggers the detection member.

[0408] As Figure 64 shown, the first transmission protrusion 351q, the second transmission protrusion 352q, and the third transmission protrusion 353q are arranged at intervals in the rotation direction of the transmission rotating member 35q. During the rotation of the transmission rotating member 35q, after the first transmission inclined surface 3511q, the second transmission inclined surface 3521q, and the third transmission inclined surface 3531q of the transmission rotating member 35q contact the driven member 42q, they will all disengage from the driven member 42q.

[0409] A reset elastic member 45q is installed between the upper end of the detected member 4q and the upper wall of the first track 1211q. The reset elastic member 45q is used to provide a downward elastic force to the detected member 4q so that the detected member 4q can remain in the non-detection position when not subject to other forces or has a tendency to move to the non-detection position. When the driven member 42q disengages from the first transmission inclined surface 3511q, the second transmission inclined surface 3521q, and the third transmission inclined surface 3531q, under the action of the reset elastic member 45q, the detected member 4q moves downward from the detection position to the non-detection position and stops triggering the detection member. In this embodiment, the upper wall of the first track 1211q is formed by the abutting plate 1212q, and the abutting plate 1212q is fixedly installed at the upper end of the first track 1211q by welding or buckling, thereby closing the opening at the upper end of the first track 1211q.

[0410] As Figure 64 and Figure 65As shown, in this embodiment, a connection method between the flexible member 36q and the second rotating member 32q is disclosed. At the upper end of the first winding portion 322q of the second rotating member 32q, a first disk body 323q is coaxially arranged. The radius of the first disk body 323q is greater than that of the first winding portion 322q. An insertion portion 324q is arranged on the first disk body 323q. The insertion portion 324q is formed by being recessed and extending from the outer circumferential surface of the first disk body 323q along the radial direction of the first disk body 323q towards the direction close to the rotation axis of the first disk body 323q. The insertion portion 324q has a first limiting wall 3241q and a second limiting wall 3242q which are oppositely arranged in the circumferential direction. At one end of the first limiting wall 3241q away from the rotation axis of the first disk body 323q in the radial direction, a first limiting convex portion 3243q is arranged. At one end of the second limiting wall 3242q away from the rotation axis of the first disk body 323q in the radial direction, a second limiting convex portion 3244q is arranged. The first limiting convex portion 3243q and the second limiting convex portion 3244q are oppositely arranged. There is a first interval between the first limiting convex portion 3243q and the second limiting convex portion 3244q in the circumferential direction. There is a second interval between the first limiting wall 3241q and the second limiting wall 3242q in the circumferential direction, and the second interval is greater than the first interval. The opposite surface of the first limiting convex portion 3243q and the second limiting convex portion 3244q is an arc surface.

[0411] As Figure 64 and Figure 65 shown, a plug-in portion 361q is fixedly connected to the first end of the flexible member 36q. The plug-in portion 361q includes a rod portion 3611q and a first limiting portion 3612q. The rod portion 3611q extends in the third direction. The first limiting portion 3612q is fixedly arranged at the upper end of the rod portion 3611q. The lower end of the rod portion 3611q is fixedly connected to the right end of the flexible member 36q (such as by welding, bonding, tight fitting, etc.). The diameter of the first limiting portion 3612q is greater than the diameter of the rod portion 3611q and the second interval. The diameter of the rod portion 3611q is greater than the first interval and less than or equal to the second interval. In this embodiment, the diameter of the rod portion 3611q is preferably equal to the second interval.

[0412] As Figure 64 and Figure 65As shown, when inserting the insertion part 361q into the insertion joint part 324q, align the rod part 3611q with the first interval between the first limiting convex part 3243q and the second limiting convex part 3244q, and press the rod part 3611q along the radial direction towards the direction close to the rotation axis of the first rotating part. Since the radius of the rod part 3611q is greater than the first interval, pressing the rod part 3611q causes elastic deformation of the first limiting convex part 3243q and the second limiting convex part 3244q, resulting in an increase in the first interval, so that the rod part 3611q can smoothly cross over the first limiting convex part 3243q and the second limiting convex part 3244q and enter between the first limiting wall 3241q and the second limiting wall 3242q. Since the diameter of the rod part 3611q is equal to the second interval, the rod part 3611q is limited in the circumferential direction by the first limiting wall 3241q and the second limiting wall 3242q, preventing the rod part 3611q from moving relative to the first rotating part in the circumferential direction. At the same time, when the rod part 3611q is subjected to a force in the radial direction towards the direction away from the rotation axis of the first rotating part, a force sufficient to cause elastic deformation of the first limiting convex part 3243q and the second limiting convex part 3244q is required to disengage from the insertion joint part 324q. Therefore, it can play a limiting effect on the insertion part 361q in the radial direction and prevent the insertion part 361q from disengaging from the insertion joint part 324q.

[0413] It is easy for those skilled in the art to think that the insertion part 331q can also be arranged at the second end part (left end) of the flexible part 36q, and the insertion joint part 324q can also be arranged on the driving rotating part 35q to achieve the effect of facilitating installation and assembly.

[0414] Embodiment Fifteen:

[0415] Without special instructions, the structure of the developing cartridge 1 in this embodiment is the same as that in Embodiment Twelve.

[0416] As Figures 66 to 74 shown, the difference between this embodiment and Embodiment Twelve lies in that the driving assembly and the transmission assembly are different.

[0417] As Figure 67As shown, in this embodiment, the driving assembly further includes a first idler gear 25r and a second idler gear 26r, which are rotatably supported by the cartridge body 10. The first idler gear 25r includes a first large tooth portion 251r and a first small tooth portion 252r. In the first direction, the first small tooth portion 252r is closer to the first end 11 than the first large tooth portion 251r. The second idler gear 26r includes a second large tooth portion 261r and a second small tooth portion 262r. In the first direction, the first large tooth portion 251r is farther from the first end 11 than the first small tooth portion 252r. The first large tooth portion 251r meshes with the driving gear 212 to receive power and rotate. The first small tooth portion 252r meshes with the second large tooth portion 261r to transmit power to the second idler gear 26r. The second large tooth portion 261r includes a tooth missing portion 2611r, and the tooth missing portion 2611r is used to disconnect the transmission with the first idler gear 25r.

[0418] As Figures 66 to 70 shown, the transmission assembly includes a transmission member 31r and a flexible member 36r. In the first direction, the distance between the transmission member 31r and the second end 12 is greater than the distance between the transmission member 31r and the first end 11. Preferably, the transmission member 31r is rotatably located at the first end 11, and its rotation axis extends in the first direction. The transmission member 31r includes a first tooth portion 311r and a first connecting portion 313r. The first connecting portion 313r is provided on the end face of the first tooth portion 311r away from the first end 11. The first connecting portion 313r is in a protruding shape extending in the first direction, preferably a cylindrical protrusion. The first connecting portion 313r is disposed offset from the rotation axis of the transmission member 31r (i.e., eccentrically disposed). The first tooth portion 311r meshes with the second small tooth portion 262r to receive power and rotate. The number of gears and the meshing relationship between the gears of the driving assembly in this embodiment are not limited and can be set according to actual needs.

[0419] As Figures 66 to 70As shown, in this embodiment, the flexible member 36r, as the member to be detected, directly triggers the detecting member 900. The flexible member 36r extends in the first direction and is movably supported by the cartridge 10. A guiding groove extending in the first direction is provided on the cartridge 10, which can guide the flexible member 36r to perform linear movement in the first direction. A first fixing portion 115 is further provided on the cartridge 10. The first fixing portion 115 is used to prevent the flexible member 36r from falling off. The first fixing portion 115 is preferably a through hole extending in the first direction. The first fixing portion 115 is provided at the fourth end 14. The flexible member 36r passes through the first fixing portion 115 and can move relative to the first fixing portion 115. The first fixing portion 115 can be single or multiple. In this embodiment, it is preferably multiple. The flexible member 36r includes a first section 361r and a second section 363r. The first section 361r is located at the first end 11 and extends in a direction close to the developing roller 131. A second connecting portion 362r is provided on the first section 361r. The second connecting portion 362r is an end of the flexible member 36r. The second connecting portion 362r is in the shape of a hole. The second connecting portion 362r cooperates with the first connecting portion 313r so that the flexible member 36r is connected to the transmission member 31r. When the transmission member 31r rotates, the flexible member 36r moves relative to the cartridge 10, and at least part of the flexible member 36r performs linear movement in the first direction. The second connecting portion 362r can move between a first position and a second position following the transmission member 31r. In the second direction, the first position is farther from the developing roller 131 than the second position.

[0420] As Figure 69 and Figure 70As shown, the second section 363r is located at the second end 12 and extends in the direction approaching the developing roller 131. The second end 12 is provided with a second cover 121, and the second section 363r is movably supported by the second cover 121. The second cover 121 is provided with a second fixing portion 1211r, and the second fixing portion 1211r is a through hole, which is used to prevent the second section 363r from falling off. The second cover 121 is provided with a first support portion 1212r and a second support portion 1213r. Along the second direction, the first support portion 1212r is farther from the developing roller 131 than the second support portion 1213r, and the first support portion 1212r is disposed adjacent to the second fixing portion 1211r. The second cover 121 is further provided with a plurality of second limiting protrusions 1214r for preventing the second section 363r from detaching. The plurality of second limiting protrusions 1214r are distributed in a staggered manner, and the second section 363r is located between the plurality of second limiting protrusions 1214r. A third connecting portion 1215r is disposed adjacent to the second support portion 1213r of the second cover 121, and the third connecting portion 1215r is preferably a cylindrical protrusion. The second section 363r includes a triggering portion 364r and a fourth connecting portion 365r. The fourth connecting portion 365r is the other end of the flexible member 36r, and the fourth connecting portion 365r is in the shape of a hole. The third connecting portion 1215r and the fourth connecting portion 365r cooperate to fix the second section 363r by the second cover 121. In this embodiment, it is preferably that the height of the connection portion between the third connecting portion 1215r and the fourth connecting portion 365r in the third direction is lower than the height of the second support portion 1213r. Along the second direction, at least a part of the triggering portion 364r is located between the first support portion 1212r and the second support portion 1213r. The triggering portion 364r is used to trigger the detecting member 900 so that the image forming apparatus can identify the developing cartridge 1. The triggering portion 364r has a relaxed state in which the detecting member 900 is not triggered and a tense state in which the detecting member 900 is triggered. When the second connecting portion 362r is at the first position, the triggering portion 364r is in the relaxed state. When the second connecting portion 362r rotates to the second position following the transmission member 31r, the triggering portion 364r is in the tense state. In some embodiments, the first support portion 1212r and the second support portion 1213r can be directly disposed on the cartridge body 10 and located at the second end 12.

[0421] The following is the process of the flexible member 36r triggering the detecting member 900 in this embodiment:

[0422] As Figures 71 to 74 shown, when the developing cartridge 1 is installed in the image forming apparatus and the driving portion 21 does not receive the power output by the image forming apparatus, the transmission member 31r does not rotate, the flexible member 36r does not move relative to the cartridge body 10, the second connecting portion 362r is at the first position, and the triggering portion 364r is in the relaxed state.

[0423] When the driving part 21 starts to receive the power output by the image forming apparatus, the driving part 21 transmits the power to the transmission member 31r. The transmission member 31r starts to rotate and drives the second connecting part 362r to start rotating. The second connecting part 362r rotates and moves closer from the first position to the second position. During this process, the second connecting part 362r drives the flexible member 36r to move rightward in the first direction relative to the cartridge 10. As a result, the triggering part 364r takes the first support part 1212r and the second support part 1213r as the support points and gradually changes from the relaxed state to the taut state. During the transformation process, the flexible member 36r is in sliding contact with the first support part 1212r, and the triggering part 364r is in direct contact with the detecting member 900, thereby driving the detecting member 900 to move. When the second connecting part 362r rotates to the second position, the triggering part 364r presents a completely taut state, and the triggering part 364r completely triggers the detecting member 900.

[0424] When the transmission member 31r continues to drive the second connecting part 362r to rotate, the second connecting part 362r rotates from the second position to the first position. At this time, the triggering part 364r changes from the taut state to the relaxed state, and under the action of the detecting member 900, the flexible member 36r moves leftward in the first direction. When the second connecting part 362r follows the transmission member 31r to rotate to the second position, the triggering part 364r changes to the taut state again and triggers the detecting member 900 again. After the detection is completed, the transmission member 31r disengages from the second idler gear 26r. The number of detections in this embodiment is not limited and can be set according to actual requirements.

[0425] It can be known that when triggering the detecting member 900, the taut state of the triggering part 364r can be a completely taut state or a partially taut state.

[0426] Optionally, in order to enable the triggering part 364r to smoothly change from the taut state to the relaxed state, an elastic member such as a tension spring or a compression spring can be added. When triggered, the elastic member deforms, and when the triggering is released, the elastic force of the elastic member causes the triggering part 364r to change its state.

[0427] As a variant of this embodiment, the difference lies in that in this variant, the first section 361r of the flexible member 36r is wound around the transmission member 31r.

[0428] Such as Figures 75 to 78As shown, the transmission member 31r includes a first tooth portion 311r, a protrusion portion 314r, and a first connection portion 315r. The first tooth portion 311r meshes with the second idler gear 26r to rotate the transmission member 31r. The protrusion portion 314r is provided on the end face of the first tooth portion 311r away from the first end 11. The extending direction of the protrusion portion 314r intersects with the first direction, that is, the protrusion portion 314r protrudes in the first direction and radially relative to the first tooth portion 311r, and the top of the protrusion portion 314r is smaller than the bottom, that is, in this embodiment, the protrusion portion 314r is generally an eccentric conical shape, the bottom is the end of the protrusion portion 314r close to the first end 11 along the first direction, and the top is the other end along the first direction. A first connection portion 315r is provided at the bottom of the protrusion portion 314r. The first connection portion 315r is preferably a through hole. The first connection portion 315r is fixedly connected to the second connection portion 362r to connect the transmission member 31r to the flexible member 36r. The first section 361r can be wound around the protrusion portion 314r when the transmission member 31r rotates.

[0429] As Figures 75 to 78[[END shown, before the transmission member 31r receives power and rotates, the first section 361r is close to the bottom of the protrusion portion 314r, and the trigger portion 364r at the second end 12 is in a relaxed state. When the transmission member 31r receives power and starts to rotate, the first section 361r gradually winds around the protrusion portion 314r, and winds from the bottom to the direction close to the top. During the winding process of the first section 361r, the flexible member 36r moves to the right along the first direction so that the trigger portion 364r changes from a relaxed state to a tightened state and triggers the detection member 900. Since the protrusion portion 314r is inclined, the first section 361r cannot always wind around the protrusion portion 314r. When the transmission member 31r continues to rotate, when the first section 361r winds to the top of the protrusion portion 314r, the first section 361r scatters from the top to the bottom, and the flexible member 36r moves to the left along the first direction under the action of the detection member 900, and the trigger portion 364r changes from a tightened state to a relaxed state and releases the trigger. After the transmission member 31r continues to rotate, the first section 361r winds from the bottom to the top again. After the transmission member 31r stops rotating, the flexible member 36r remains stationary.

[0430] As ​ and ​ shown, in this embodiment, a guide member 116 is further provided on the developing cartridge 1. Specifically, the guide member 116 is provided at the first end 11 and is located on the rear side of the transmission member 31r in the second direction. The guide member 116 has a guide groove for the first section 361r to pass through / move, which is used to define the movement range / position of the first section 361r, and is convenient for guiding the first section 361r to wind around the protrusion portion 314r to drive the flexible member 36r to move along the first direction.

[0431] The other structures of the developing cartridge 1 in this embodiment are the same as those in the first embodiment, and will not be described in detail here.

[0432] Embodiment Sixteen:

[0433] Unless otherwise specified, the structures in this embodiment are the same as those in the fifteenth embodiment.

[0434] The difference between this embodiment and the fifteenth embodiment lies in that the second idler gear 26s and the transmission member 31s are bevel gears, the flexible member 36r is not connected to the transmission member 31s, and the structure of the transmission member 31s is different.

[0435] As ​ shown, the second idler gear 26s (equivalent to the first rotating member) includes a second large tooth portion 261s and a second small tooth portion 262s. The second large tooth portion 261s includes a tooth missing portion 2611s, and the second small tooth portion 262s is a bevel tooth. In the first direction, the distance between the transmission member 31s and the second end 12 is greater than the distance between the transmission member 31s and the first end 11. The transmission member 31s includes a first tooth portion 311s and a pressing portion 316s. The first tooth portion 311s is a bevel tooth. The first tooth portion 311s meshes with the second small tooth portion 262s to receive power and rotate. The rotation axis of the transmission member 31s intersects the first direction. In this embodiment, it is preferably parallel to the third direction. The pressing portion 316s is a radially protruding protrusion, and the pressing portion 316s is used to press the flexible member 36r.

[0436] As ​ shown, the first end 11 is provided with a first support column 106. The first support column 106 extends in the third direction. The transmission member 31s is rotatably supported by the first support column 106. A first connection portion 117 is also provided at the first end 11. The first connection portion 117 is fixedly connected to the second connection portion 362r of the flexible member 36r. Along the second direction, the pressing portion 316s is located between the first connection portion 117 and the fourth end 14.

[0437] As ​ shown, when the transmission member 31s does not rotate, the pressing portion 316s does not contact or only slightly contacts the first section 361r of the flexible member 36r, and the first section 361r located at the first end 11 is in a straight state. When the transmission member 31s rotates, the pressing portion 316s abuts against the first section 361r, causing the first section 361r to change, that is, the first section 361r is bent or in a curved state after being pressed. While the first section 361r is being pressed, it drives the flexible member 36r to move to the right in the first direction, so that the trigger portion 364r changes from a relaxed state to a taut state and triggers the detection member 900. After the transmission member 31s continues to rotate, the pressing portion 316s releases the abutment against the first section 361r, and the trigger portion 364r changes to a relaxed state and releases the trigger on the detection member 900.

[0438] Example XVII:

[0439] Unless otherwise specified, the structure in this example is the same as that in Example XV.

[0440] As ​ shown, the difference between this example and Example XV lies in the driving component and the transmission component.

[0441] As ​ shown, in this example, the driving component includes a driving part 21, a developing gear 22, a powder feeding gear 23, a stirring gear 24, a first idler gear 25, a second idler gear 26, and a third idler gear 27. The developing gear 22 and the powder feeding gear 23 are engaged with the driving gear 212 to receive power and rotate. The first idler gear 25 is engaged with the driving gear 212 to receive power, and the first idler gear 25 transmits the power to the stirring gear 24 through the second idler gear 26 and the third idler gear 27. In this example, the first idler gear 25, the second idler gear 26, the third idler gear 27, and the stirring gear 24 are all second-stage gears to meet the required rotational speed of this example. The number of gears and the meshing relationship of the transmission component in this example are not limited and can be set according to actual needs.

[0442] As ​ shown, the transmission component includes a first rotating member 31t, a second rotating member 32t (equivalent to a transmission member), and a flexible member 36r. The first rotating member 31t is located at the first end 11. The first rotating member 31t includes a first tooth portion 311t and a first driving protrusion 312t. In the first direction, the first tooth portion 311t is farther from the second end 12 than the first driving protrusion 312t. The first tooth portion 311t includes a toothless portion. The first tooth portion 311t is used to engage with the stirring gear 24 so that the first rotating member 31t can rotate following the stirring gear 24. When the toothless portion on the first tooth portion 311t faces the stirring gear 24, the first rotating member 31t no longer rotates following the stirring gear 24. The first driving protrusion 312t protrudes in the first direction. In this example, the first driving protrusion 312t is preferably multiple, and the shapes of the multiple first driving protrusions 312t are not completely the same. In this example, the first driving protrusion 312t is preferably three.

[0443] As ​As shown, a third support post 103 is provided on the cartridge body 10. The third support post 103 is preferably a cylinder extending in the third direction. The second rotating member 32t is rotatably supported by the third support post 103. The second rotating member 32t is swung by the abutment of the first rotating member 31t, and its swinging axis is perpendicular to the first direction. The second rotating member 32t includes a first connecting portion 321t and an abutting protrusion 322t. The first connecting portion 321t and the abutting protrusion 322t are respectively protrusions of the second rotating member 32t in the radial direction. When the first rotating member 31t rotates following the stirring gear 24, the first driving protrusion 312t abuts against the abutting protrusion 322t, causing the second rotating member 32t to swing relative to the cartridge body 10. Further, the abutting protrusion 322t swings towards the direction close to the developing roller 131, and the first connecting portion 321t swings away from the developing roller 131 (clockwise swing when observed from top to bottom). A first elastic member 33t is also provided on the developing cartridge 1. The first elastic member 33t is preferably a torsion spring. The first elastic member 33t is in contact with the second rotating member 32t. An abutting end 331t is provided on the first elastic member 33t. An abutting block 107 protruding in the third direction is provided on the cartridge body 10. The abutting end 331t is abutted by the abutting block 107. When the second rotating member 32t swings, the first elastic member 33t undergoes elastic deformation. After the abutting protrusion 322t of the second rotating member 32t is disengaged from the first driving protrusion 312t of the first rotating member 31t, the first elastic member 33t releases the elastic force to cause the second rotating member 32t to swing in the reverse direction (counterclockwise swing) to reset.

[0444] As Figures 84 to 86As shown, the structure of the flexible member 36r in this embodiment is the same as that in the fifteenth embodiment, and it also directly triggers the detection member 900 as the detected member. The flexible member 36r can be made of plastic material, or metal material, resin material, etc. This embodiment does not limit the material of the flexible member 36r, as long as the required functions can be completed. The flexible member 36r extends in the first direction. The flexible member 36r includes a first section 361r and a second section 363r. A second connecting portion 362r is provided at the end of the first section 361r. The second section 363r includes a triggering portion 364r and a fourth connecting portion 365r. The fourth connecting portion 365r is provided at the end of the second section 363r. The second connecting portion 362r is connected to the first connecting portion 321t of the second rotating member 32t, which can be connected by sleeving, or by welding, gluing or other means. When the second rotating member 32t swings under the abutment of the first rotating member 31t, the flexible member 36r moves following the movement of the second rotating member 32t. A first guide rail 152t extending in the first direction is provided on the fifth end 15. A part of the flexible member 36r is located within the first guide rail 152t. The first guide rail 152t guides the flexible member 36r to move along a preset path. The guide rail surface within the first guide rail 152t is preferably a smooth surface to reduce the frictional force between the flexible member 36r and the first guide rail 152t.

[0445] As Figure 86 shown, a second guide rail 1213t and a third connecting portion 1215t are further provided on the second cover 121. The second guide rail 1213t extends along the first direction and has a bent portion in the second direction. The bent portion is located at the left end of the second guide rail 1213t. In the second direction, the bent portion is located on the front side of the third connecting portion 1215t. Preferably, the guide rail surface within the second guide rail 1213t is a smooth surface. The third connecting portion 1215t is a protruding structure. A part of the flexible member 36r is also located within the second guide rail 1213t, such that the flexible member 36r is guided by the second guide rail 1213t to move. The bent portion on the second guide rail 1213t causes the second section 363r of the flexible member 36r to bend and extend in the second direction, that is, to have a length in the second direction. The fourth connecting portion 365r is connected to the third connecting portion 1215t, which can be connected by sleeving, or by welding, gluing or other means. The portion of the second section 363r between the fourth connecting portion 365r and the bent portion is the triggering portion 364r. The triggering portion 364r can directly trigger the detection member 900, enabling the image forming apparatus to recognize the developing cartridge 1. When the flexible member 36r moves following the swing of the second rotating member 32t, the first section 361r of the flexible member 36r moves in the second direction away from the developing roller 131, and further causes the flexible member 36r to slide relative to the cartridge body 10 to the right on the first guide rail 152t and the second guide rail 1213t. Further, the second section 363r of the flexible member 36r is pulled, and the triggering portion 364r changes from a relaxed state to a taut state.

[0446] As Figure 82 and Figure 84 shown, a cover member 150 is provided on the cartridge body 10. The cover member 150 is used to cover a part of the flexible member 36r and the second rotating member 32t, so that the flexible member 36r and the second rotating member 32t are not easily damaged or disengaged.

[0447] As Figure 87 and Figure 88 shown, after the driving part 21 receives the power output by the image forming apparatus and rotates, the first rotating member 31t receives the power and rotates. The first driving protrusion 312t abuts against the abutting protrusion 322t, so that the second rotating member 32t swings. The first connecting part 321t connected to the first section 361r swings in a direction away from the developing roller 131, and further causes the flexible member 36r to move, so that the triggering part 364r changes from a relaxed state to a taut state, and then triggers the detecting member 900. The first elastic member 33t deforms and stores elastic force. When the second rotating member 32t loses the abutment of the first rotating member 31t, the first elastic member 33t releases the elastic force to make the second rotating member 32t swing in the reverse direction. The triggering part 364r is pressed down by the detecting member 900 and changes from a taut state to a relaxed state, and the flexible member 36r slides leftward in the first direction. Since a plurality of first driving protrusions 312t are provided on the first rotating member 31t, the triggering part 364r can trigger the detecting member 900 multiple times. After the detection is completed, the first rotating member 31t no longer rotates following the stirring gear 24.

[0448] In some embodiments, when the driving part 21 does not receive the power output by the image forming apparatus, the first rotating member 31t abuts against the second rotating member 32t, the triggering part 364r is in a taut state, and after the first rotating member 31t receives the transmitted power and rotates, the first rotating member 31t loses the abutment with the second rotating member 32t. The number of detection triggers and the trigger sequence are not limited in this embodiment and can be set according to actual needs.

[0449] As Figure 89As shown in the figure, in order to ensure that the triggering part 364r can smoothly change from the tightened state to the relaxed state, a reset component can be further provided. A third guide rail 153t and a first connecting protrusion 108 are provided on the cartridge 10. The third guide rail 153t extends in the first direction, and the first connecting protrusion 108 protrudes in the third direction. The reset component preferably includes a second flexible member 35t and a second elastic member 34t. The third guide rail 153t guides the movement of the second flexible member 35t. The second flexible member 35t includes a third end 351t and a fourth end 352t that are respectively located at both ends of the second flexible member 35t in the first direction. The fourth end 352t is hooked to the triggering part 364r. The second elastic member 34t is preferably a tension spring. One end of the second elastic member 34t in the first direction is connected to the first connecting protrusion 108, and the other end is connected to the third end 351t. The second elastic member 34t can be stretched and restored in the first direction. When the triggering part 364r changes from the relaxed state to the tightened state, the triggering part 364r drives the second flexible member 35t to move relative to the cartridge 10, and the second elastic member 34t is stretched and stores elastic force. When the second rotating member 32t loses the abutment of the first rotating member 31t, the second elastic member 34t releases the elastic force to cause the second flexible member 35t to move in the reverse direction. The second flexible member 35t drags the triggering part 364r, so that the triggering part 364r changes from the tightened state to the relaxed state.

[0450] In this embodiment, after the flexible member 36r receives power from near the first end 11, the triggering part 364r located at the second end 12 is directly used to trigger the detecting member 900, which simplifies the structure of the developing cartridge 1 and is beneficial to controlling the production cost of the developing cartridge 1.

[0451] In some other embodiments, such as Figure 90 and Figure 91 As shown in the figure, the rotation axis of the driving part 21 can intersect with the first direction. The rotation axis of the driving part 21 is inclined relative to the first direction, and the inclination angle is 0 to 20°. In this embodiment, it is preferably 15°. The driving part 21 includes a power receiving part 211 and a driving gear 212. The power receiving part 211 is used to receive the power output by the image forming apparatus, and the driving gear 212 is used to transmit the power to the remaining gears in the transmission assembly. The driving gear 212 is trapezoidal cylindrical, and preferably the diameter of the part of the driving gear 212 away from the power receiving part 211 in the first direction is larger than the diameter near the power receiving part 211. Correspondingly, the developing gear 22, the powder feeding gear 23 and the first idler gear 25 meshing with the driving gear 212 are all trapezoidal cylindrical to ensure that the developing gear 22, the powder feeding gear 23 and the first idler gear 25 stably receive power.

[0452] Embodiment Eighteen

[0453] Unless otherwise specified, the structure in this embodiment is the same as the structure in Embodiment Fifteen.

[0454] As shown in Figures 92 to 111 FIG. [ID], the difference between this embodiment and the fifteenth embodiment lies in that the transmission components are different.

[0455] As shown in Figure 93 FIG. [ID], the box body 10 is provided with a first guide rail 151u, a first track 152u, a second guide rail 153u, a second track 154u, a first support column 103, a second support column 109, and a fifth fixing part 155u at the fifth end 15. The first guide rail 151u and the second guide rail 153u penetrate the entire box body 10 in the first direction. The right side of the first guide rail 151u in the first direction is connected to the first track 152u. The depth of the first track 152u in the third direction is greater than the depth of the first guide rail 151u in the third direction. The right side of the second guide rail 153u in the first direction is connected to the second track 154u. The depth of the second track 154u in the third direction is greater than the depth of the second guide rail 153u in the third direction. The first guide rail 151u and the first track 152u are closer to the fourth end 14 than the second guide rail 153u and the second track 154u in the second direction.

[0456] As shown in Figure 93 FIG. [ID], a first support column 103 and a second support column 109 are further provided on the side of the fifth end 15 close to the first end 11. The first support column 103 and the second support column 109 are columnar parts extending upward in the third direction. The fifth fixing part 155u is arranged on the right side of the second track 154u in the first direction, close to the second support column 109.

[0458] As shown in Figure 93 and Figure 94 FIG. [ID], the first rotating member 31u is a two-stage gear, and its rotation center is parallel to the first direction. It includes a first tooth part 311u and a second tooth part 312u. The first tooth part 311u meshes with the stirring gear 24, and the second tooth part 312u meshes with the second rotating member 32u.

Among them, in the third direction, the third tooth portion 328u and the first unlocking protrusion 329u are located below the plurality of driving portions, and the plurality of driving portions are located on the same horizontal plane in the horizontal direction. The third tooth portion 328u is a tapered tooth and includes a tooth missing portion 3281u. The radial diameters of the plurality of driving portions are greater than the diameters of the plurality of gaps. The first unlocking protrusion 329u is formed by the third tooth portion 328u protruding radially outward. In the circumferential direction, it is located between the first driving portion 321u and the second driving portion 322u. The second rotating member 32u is installed on the first support column 103, and its rotation axis is parallel to the third direction.

[0460] As Figure 96 shown, the translating member 33u includes a main body portion 331u, a contact portion 332u, and a third fixing portion 333u. The main body portion 331u of the translating member 33u can cooperate with the first track 152u and translate left and right in the first direction within the first track 152u. The unlocking member 34u includes a fixing hole 341u, a second unlocking protrusion 342u, and a locking portion 343u. The unlocking member 34u can be fixed on the second support column 109 through the fixing hole 341u and can rotate around the second support column 109. Its rotation axis is parallel to the third direction. The second unlocking protrusion 342u can be in abutting cooperation with the first unlocking protrusion 329u on the second driving gear 52 so that the unlocking member 34u rotates around the second support column 109. The accelerating member 35u includes an accelerating main body 351u, a locking recess 352u, a fourth fixing portion 353u, and a receiving recess 354u. The accelerating main body 351u can cooperate with the second track 154u on the box body 10, and the accelerating main body 351u can move left and right in the second track 154u in the first direction. When the accelerating member 35u is installed in the second track 154u, one end of the variable-speed elastic member 37u abuts against the left side wall of the second track 154u in the first direction, and one end abuts against the accelerating member 35u through the receiving recess 354u. The locking portion 343u on the unlocking member 34u can cooperate with the locking recess 352u.

[0461] As Figure 93 、 Figure 97 and Figure 98As shown, the flexible member 36u, as the detected member, directly triggers the detecting member 900. It is an integral rope-like member, which includes a first end portion 361u and a second end portion 362u. The first end portion 361u is connected to the third fixing portion 333u on the translating member 33u. Then, the main body portion of the flexible member 36u bypasses the second end 12 through the first guide rail 151u and then passes through the second guide rail 153u. Then, the second end portion 362u is connected to the fourth fixing portion 353u on the accelerating member 35u. That is, for the flexible member 36u, its first end portion 361u is connected to the translating member 33u, and its second end portion 362u is connected to the accelerating member 35u. Its main body is installed within the first guide rail 151u and the second guide rail 153u. The flexible member 36u at the bypassed second end 12 is the triggering portion 363u. When projected from top to bottom in the third direction, the projection of the flexible member 36u is in a "U" shape with the opening facing right.

[0462] As Figure 97 and Figure 98 As shown, a first correction groove 1211u, a first correction hole 1212u, and a second correction groove 1213u are further provided on the second cover 121. The first correction groove 1211u, the first correction hole 1212u, and the second correction groove 1213u are provided above the second cover 121 in the third direction. The second correction groove 1213u is used to fix the flexible member 36u passing through the first guide rail 151u. The flexible member 36u passing through the second correction groove 1213u passes through the first correction hole 1212u and then through the first correction groove 1211u, and then enters the second guide rail 153u. In this embodiment, the part of the flexible member 36u between the second correction groove 1213u and the first correction hole 1212u is the triggering portion 363u. In this embodiment, the first correction groove 1211u, the first correction hole 1212u, and the second correction groove 1213u are provided to better fix the flexible member 36u at the second end 12, and to facilitate the triggering portion 363u of the flexible member 36u at the second end 12 to better play its role when the flexible member 36u is installed in the first guide rail 151u and the second guide rail 153u. In other embodiments, the first correction groove 1211u, the first correction hole 1212u, and the second correction groove 1213u may not be provided, and other intermediate structures may be provided to fix the flexible member 36u, as long as the flexible member 36u can play its corresponding role, and the specific structure is not limited too much here.

[0463] A detecting member 900 is further provided in the image forming apparatus, which includes a detecting portion 910. When the developing cartridge 1 and the drum assembly are installed in the image forming apparatus together, the triggering portion 363u causes the detecting member 900 to move, and further causes the image forming apparatus to receive the signal transmitted by the detecting member 900, thereby identifying the developing cartridge 1.

[0464] As Figures 98 to 102As shown, it is the initial state where the developing cartridge 1 and the drum assembly are loaded into the image forming apparatus and cooperate with the detection member.

[0465] As Figure 98 shown, it is the initial state of the developing cartridge 1. At this time, the translation member 33u is installed in the first rail 152u, the first end 361u of the flexible member 36u is connected to the third fixing portion 333u on the translation member 33u, and the translation member 33u is in the first position within the first rail 152u, that is, the translation member 33u is in a position close to the right side within the first rail 152u, that is, the translation member 33u is at a certain distance from the left side of the first rail 152u in the first direction. At this time, the contact portion 332u of the translation member 33u and the first driving portion 321u of the second rotating member 32u are in contact. The accelerating member 35u is located within the second rail 154u. At this time, the second end 362u of the flexible member 36u is connected to the fourth fixing portion 353u on the accelerating member 35u. At this time, the variable speed elastic member 37u is located between the accelerating member 35u and the inner wall on the left side of the second rail 154u in the second direction and the variable speed elastic member 37u is in a compressed state. The unlocking member 34u is in the locked position, and the locking portion 343u thereon is located within the locking recess 352u of the accelerating member 35u, that is, in the first direction, at least a part of the locking portion 343u of the unlocking member 34u coincides with the accelerating member 35u in the first direction, and a fifth fixing portion 155u is further provided on the cartridge body 10. The fifth fixing portion 155u at least partially coincides with the projection of the unlocking member 34u in the third direction. The fifth fixing portion 155u is used for further fixing and limiting the unlocking member 34u to prevent the unlocking member 34u from being overly engaged with the accelerating member 35u and being difficult to unlock. In other embodiments, the fifth fixing portion 155u may not be provided as long as the unlocking member 34u and the accelerating member 35u can be normally engaged / unlocked.

[0466] When the translation member 33u is in the first position, at this time, the translation member 33u will generate a first force (tensile force) F1 acting on the flexible member 36u located within the first guide rail 151u in the first direction to the right. At this time, the flexible member 36u that turns via the second end will generate a second force (tensile force) F2 acting on the accelerating member 35u in the first direction to the left via the second guide rail 153u. And because the flexible member 36u is an integral body and the variable speed elastic member 37u is in a compressed state, the variable speed elastic member 37u will generate a third force (elastic force) F3 acting on the accelerating member 35u in the first direction to the right. The second force F2 and the third force F3 are coaxial and opposite in direction in the first direction. And when the translation member 33u is in the first position, the second force F2 is greater than the third force F3. At this time, there is a first distance H1 between the left end of the accelerating member 35u in the first direction and the left end of the second rail 154u in the first direction.

[0467] As Figure 100As shown, when the translation member 33u is in the first position, the unlocking member 34u is in the locked position, that is, the locking portion 343u cooperates with the locking recess 352u on the accelerating member 35u. However, since the second force F2 exerted by the flexible member 36u on the accelerating member 35u is greater than the third force F3 exerted by the variable-speed elastic member 37u on the accelerating member 35u, there is still a second distance H2 between the locking portion 343u and the locking recess 352u.

[0468] As Figure 101 shown, when the translation member 33u is in the first position and the contact portion 332u thereon abuts against the first driving portion 321u on the second rotating member 32u, the developing cartridge 1 is in the initial state at this time. At this time, the second tooth portion 312u on the first rotating member 31u meshes with the third tooth portion 328u on the second rotating member 32u. Specifically, when looking down along the third direction, the second tooth portion 312u meshes with the tapered tooth portion where the toothless portion 3281u contacts the third tooth portion 328u along the counterclockwise rotation.

[0469] As Figure 102 shown, when the developing cartridge 1 is in the initial state, since the translation member 33u exerts a first force F1 in the rightward direction along the first direction on the flexible member 36u within the first guide rail 151u, the triggering portion 363u of the flexible member 36u at the second end 12 is in a taut state under the action of the first force F1. When the developing cartridge 1 in the initial state is installed in the image forming apparatus, the triggering portion 363u of the flexible member 36u will act on the detecting member 900 of the image forming apparatus. Specifically, it acts on the detecting portion 910, causing the detecting member 900 to be in the swinging state L1. When the detecting member 900 is in the swinging state L1, due to gravity or the presence of a resilient member installed therein, etc., through the elastic force, the detecting member 900 will tend to return to the non-swinging state, and will exert a downward pressure on the triggering portion 363u of the flexible member 36u, the triggering portion 363u.

[0470] As Figure 103As shown, when the driving gear 41 receives the driving force of the image forming apparatus, it transmits the power to the first driving gear 51 through the transmission assembly. When the first transmission gear 51 rotates along the axis parallel to the first direction, the second tooth portion 312u transmits the power to the second rotating member 32u through the third tooth portion 328u. At this time, the second rotating member 32u rotates clockwise along the axis parallel to the third direction, that is, rotates along the rotation trajectory S1. When it rotates to the second driving portion 322u abuts against the contact portion 332u, during this process, since there is no gap between the first driving portion 321u and the second driving portion 322u in the counterclockwise direction, when the second rotating member 32u rotates clockwise along the rotation trajectory S1, the translating member 33u still remains in the first position, and generates a first force F1 on the flexible member 36u in the first guide rail 151u. The triggering portion 363u of the second end 12 still acts on the detecting portion 910 of the detecting member 900. The detecting member 900 still remains in the swinging state L1, and still generates a second force F2 on the translating member 33u in the second guide rail 153u, and the second force F2 is greater than the third force F3. The second distance H2 still exists between the locking portion 343u and the locking recess 352u. The first distance H1 remains unchanged between the left end of the accelerating member 35u in the first direction and the left end of the second track 154u in the first direction.

[0471] As Figures 104 to 106 shown, when the second rotating member 32u continues to rotate along the rotation trajectory S1 and the second driving portion 322u passes over the contact portion 332u, at this time, due to the existence of the first gap 323u, the second rotating member 32u no longer abuts against the translating member 33u. The translating member 33u no longer exerts the first force F1 on the flexible member 36u. The pressure of the detecting member 900 on the triggering portion 363u will cause the translating member 33u to move leftward in the first direction until the translating member 33u abuts against the inner wall on the left side of the first track 152u in the first direction. At this time, the translating member 33u is in the second position. Under the action of gravity / rebound force, the detecting member 900 swings clockwise from the swinging position L1 to the non-swinging position L2. At this time, since the flexible member 36u in the second guide rail 153u no longer exerts the second force F2 on the accelerating member 35u, at this time, under the action of the third force F3 exerted by the variable-speed elastic member 37u, the accelerating member 35u will move a certain distance to the right in the first direction, and this distance is the same as the second distance H2. At this time, the locking recess 352u on the accelerating member 35u fits with the locking portion 343u on the unlocking member 34u, that is, there is no second distance H2 between the locking portion 343u and the locking recess 352u. At this time, the distance between the left side of the accelerating member 35u in the first direction and the left side of the second track 154u is the third distance H3, and the third distance H3 is greater than the first distance H2. Specifically, the third distance H3 satisfies: H3 = H1 + H2, that is, the third distance H3 is equal to the sum of the first distance H1 and the second distance H2.

[0472] When the developing cartridge 1 is in the initial state, the translation member 33u is in the first position, and when installed in the image forming apparatus, the detection member 900 is in the swinging position L1. When the second rotating member 32u rotates along the rotation locus S1 until the second driving portion 322u crosses the contact portion 332u of the translation member 33u, and the translation member 33u moves along the first track 152u within the first gap 533 to the second position, at this time the detection member 900 is in the non-swinging position L2. The process of the detection member 900 from the swinging position L to the non-swinging position L2 is the process by which the image forming apparatus completes one identification of the developing cartridge 1. Since the models of the developing cartridges 1 are different and the image forming apparatuses are also different, after each developing cartridge 1 is installed in the image forming apparatus, the number of times the image forming apparatus needs to detect the developing cartridge 1 is different, that is, the number of swings that the detection member 900 needs to complete is different. At the same time, for different developing cartridges 1, the required swinging time and the speed during swinging will also be different.

[0473] As Figure 107 shown, after the detection member 900 completes the first swinging process, the first driving gear 51 continues to drive the second rotating member 32u to rotate along the rotation locus S1. When the third driving portion 324u abuts against the contact portion 332u on the translation member 33u, at this time, the translation member 33u will move leftward in the first direction within the first track 152u under the action of the third driving portion 324u, and move from the second position to the first position again. At this time, the translation member 33u generates a first force F1 in the rightward direction along the first direction on the flexible member 36u. The triggering portion 363u is straightened under the action of the first force F1 and acts on the detection portion 910 of the detection member 900, causing the detection member 900 to move from the non-swinging position L2 to the swinging position L1. At the same time, the flexible member 36u generates a second force F2 in the leftward direction along the first direction on the accelerating member 35u. The distance between the accelerating member 35u on the left side in the first direction and the second track 154u on the left side in the first direction changes from the third distance H3 to the first distance H1, and the locking portion 343u on the locking member 54 and the locking concave portion 352u on the accelerating member 35u change from the fitting state to having the second distance H2, that is, exactly the same as when the developing cartridge 1 is installed in the image forming apparatus at the initial position.

[0474] When the second rotating member 32u continues to rotate along the rotation locus S1, when the third driving portion 324u crosses the contact portion 332u and the translation member 33u reaches the second gap 325u, the translation member 33u will repeat the process of moving from the first position to the second position along the first track 152u when it is in the first gap 323u, and its state process is exactly the same, so no more details will be described here.

[0475] As Figure 108As shown, when the fourth driving part 326u crosses the translation part 33u and the translation part 33u moves from the first position to the second position within the third gap 327u, the process is exactly the same as the above process and will not be elaborated here. At this time, the locking recess 352u on the accelerating part 35u fits with the locking part 343u on the unlocking part 34u, that is, there is no second distance H2 between the locking part 343u and the locking recess 352u, and the detecting part 900 is in the non-swinging position L1.

[0476] As Figures 109 to 111 shown, when the fourth driving part 326u crosses the translation part 33u, the translation part 33u moves from the first position to the second position within the third gap 327u, and the second rotating part 32u continues to rotate along the rotation track S1. At this time, the first unlocking protrusion 329u on the second rotating part 32u abuts against the second unlocking protrusion 342u on the unlocking part 34u. After the unlocking part 34u receives the force transmitted by the second rotating part 32u through the second unlocking protrusion 342u, the unlocking part 34u will also rotate counterclockwise around the second support column 109 to the unlocking position where the locking recess 352u on the accelerating part 35u does not coincide with the projection of the locking part 343u on the locking part 54 in the first direction. At this time, under the action of the elastic force F3 of the variable-speed elastic part 37u, the accelerating part 35u moves to the right along the first direction on the second track 154u. At this time, the triggering part 363u receives the action of the third force F3 and acts on the detecting part 910, so that the detecting part 900 moves from the non-swinging position L2 to the swinging position L1. Moreover, under the action of the third force F3, the speed at which the detecting part 900 moves from the non-swinging position L2 to the swinging position L1 is greater than the speed at which the detecting part moves from the non-swinging position L2 to the swinging position L1 under the action of the first force F1. When the detecting part 900 is in the swinging position L1, the accelerating part 35u stops moving. At this time, the second rotating part 32u continues to rotate along the moving track S1. When the second tooth part 312u on the first rotating part 31u is not engaged with the third tooth part 328u, that is, when the second tooth part 312u is located at the toothless part 3281u, the first rotating part 31u and the second rotating part 32u are disengaged, and the first rotating part 31u no longer transmits power to the second rotating part 32u, and the detection process of the entire developing cartridge 1 in the image forming apparatus ends.

[0477] In this embodiment, the second distance H2 is smaller than the displacement generated in the first direction when the translational member 33u moves from the first position to the second position. The purpose is that due to errors in the assembly process and manufacturing process of the flexible member 36u, and due to the action of the first force F1 and the second force F2, the flexible member 36u installed on the box body 10 may undergo elastic deformation. The second distance H2 is used to eliminate this elastic deformation. When the translational member 33u moves from the first position to the second position, the second distance H2 is eliminated under the action of the variable-speed elastic member 37u. That is, the accelerating member 35u is moved to the right by the same distance as the second distance H2 under the action of the third force F3, that is, the flexible member 36u is pulled to the right by the length of the second distance H2. Since the second distance H2 is smaller than the displacement generated when the translational member 33u moves from the first position to the second position, when the translational member 33u is in the second position, although the accelerating member 35u pulls the flexible member 36u to the right by the length of the second distance H2, the triggering portion 363u is still in an unloaded state, that is, the detecting member 900 is still in the non-swinging position L2. However, the length of the remaining flexible member 36u, which is the difference between the displacement generated when the translational member 33u moves from the first position to the second position and the second distance H2, is just enough for the translational member 55 to drive the flexible member 36u to move when unlocked, so that the detecting member 900 moves from the non-swinging position L2 to the swinging position L1 under the action of the third force F3. That is, the purpose of setting the second distance H2 is to prevent the flexible member 36u from becoming longer due to elastic deformation / tooling errors of the flexible member. When the accelerating member 35u is unlocked and moves to the right in the first direction, the detecting member 900 moves under the action of the third force F3. However, due to the elongation of the flexible member 36u, when the accelerating member 35u moves to the right end of the second track 154u in the first direction, at this time, although the detecting member 900 moves from the non-swinging position L2 under the action of the third force F3, it stops before reaching the swinging position L1, resulting in a poor final swinging effect and affecting the identification of the developing cartridge 1 by the image forming apparatus.

[0478] Furthermore, in other embodiments, the second distance H2 may not be set as long as it can be ensured that the flexible member 36u does not undergo elastic deformation during operation, or there are no errors during production and tooling, and the detecting member 900 does not reach the swinging position L1 during the last swing, which may affect the detection result. Specific details are not limited here.

[0479] Moreover, in other embodiments, the second distance H2 may also not be set. It is only necessary to increase the length of the second track 154u in the first direction and increase the length of the variable-speed elastic member 37u, so that the displacement distance of the accelerating member 35u in the first direction is sufficient to cover the elastic deformation of the flexible member 36u or the production and tooling errors. Specific details are not limited here.

[0480] Further, the flexible member 36u is an integral rope-like member. In the present application, preferably, its material is nylon. In other embodiments, its material can be steel wire, pure cotton, etc., and specific details are not limited herein.

[0481] By providing a flexible member on the developing cartridge 1 as the member to be detected, the detection of the developing cartridge 1 by the image forming apparatus can be made more convenient, and its adjustability is higher.

[0482] Nineteenth Embodiment:

[0483] Unless otherwise specified, the structure in this embodiment is the same as that in Embodiment 1.

[0484] The difference between this embodiment and Embodiment 1 lies in that the power source of the member to be detected is different.

[0485] As Figure 115 shown, a first support column 101 is provided at the first end 11. The first support column 101 extends in a first direction away from the first end 11. The first support column 101 is cylindrical and is used to support the driving portion 21. A first opening 1012 is provided on the circumferential wall of the first support column 101. The first opening 1012 is an opening on the circumferential wall of the first support column 101, and the first opening 1012 extends in the first direction. In a second direction, a second opening 114 is provided behind the first support column 101. The second opening 114 is an opening that penetrates the side wall of the first end 11 in the first direction. A second support column 113 is provided adjacent to the second opening 114. The second support column 113 is cylindrical and extends in the first direction. In this embodiment, the second support column 113 is preferably provided in two, and the two second support columns 113 are arranged around the second opening 114. In other embodiments, the number of the second support columns 113 can be set according to actual needs.

[0486] As Figure 113 and Figure 114 shown, a first cover 111 is detachably installed at the first end 11. The first cover 111 includes a first hole 1111, a second hole 1112, a third hole 1113, and a third support column 1114. The first hole 1111 and the second hole 1112 are through holes of the first cover 111 in the first direction. In the second direction, the second hole 1112 is located behind the first hole 1111. The power receiving portion 211 is exposed through the first hole 1111. The third hole 1113 is a through hole of the first cover 111 in a third direction. The third support column 1114 extends in the first direction, and the third support column 1114 is preferably cylindrical.

[0487] As Figures 112 - 119As shown, the developing cartridge 1 further includes a triggering assembly, which is preferably arranged at the first end 11. The triggering assembly includes a force-receiving member 71a, a restricting member 72a, and a first elastic member 73a. The force-receiving member 71a is movably supported by the first support post 101. At one end of the force-receiving member 71a extending away from the first end 11 in the first direction, there are force-receiving protrusions 711a extending in the first direction. In this embodiment, preferably two force-receiving protrusions 711a are provided, and the force-receiving protrusions 711a have a surface to be abutted (a bevel or an arc surface, preferably an arc surface in this embodiment), and the extending direction of the abutting surface intersects with the first direction. At least a part of the force-receiving member 71a is located within the driving portion 21. There are through holes penetrating in the first direction on the power receiving portion 211. Preferably two through holes are provided. The force-receiving protrusions 711a are exposed through the through holes, and the force-receiving protrusions 711a move by receiving an external force, that is, the force-receiving protrusions 711a are abutted by the power output member 920 of the image forming apparatus and move leftward in the first direction relative to the cartridge body 10.

[0488] As Figures 112 - 119 As shown, the restricting member 72a is movably supported by the first support post 101. In the first direction, the restricting member 72a is closer to the first end 11 than the force-receiving member 71a. The restricting member 72a is in contact with the force-receiving member 71a. When the force-receiving member 71a is stressed in the first direction, the restricting member 72a follows the force-receiving member 71a and moves leftward in the first direction. The restricting member 72a is provided with a restricting protrusion 721a, and the restricting protrusion 721a protrudes radially from the restricting member 72a. The restricting protrusion 721a protrudes from the first support post 101 through the first opening 1012 on the first support post 101. The restricting protrusion 721a is provided with a first surface, and the first surface is a bevel or an arc surface. The first elastic member 73a is arranged within the first support post 101. The first elastic member 73a is preferably a compression spring, and can also be an elastic medium such as a sponge or a tension spring. In the first direction, the first elastic member 73a is located between the restricting member 72a and the first end 11. The first elastic member 73a can be abutted by the restricting member 72a and compressed. The acting force of the first elastic member 73a can keep the force-receiving member 71a at a position where the force-receiving protrusions 711a are exposed outside the through holes before being subjected to an external force, facilitating the abutment with the power output member 920.

[0489] As Figures 112 to 119As shown, the developing cartridge 1 further includes an energy storage assembly for applying power to the detected member 4w to trigger the detecting member 900. The energy storage assembly includes an energy storage rotating member 81a, an energy storage member 83a, a force applying member 82a, a translating member 85a, and a first transmission rod 84a. The energy storage rotating member 81a is rotatably supported by the first cover 111. The energy storage rotating member 81a is inserted into the second hole 1112 of the first cover 111. In some embodiments, the energy storage rotating member 81a may be rotatably supported by the cartridge body 10. The energy storage rotating member 81a includes a first force receiving portion 811a, a force applying portion 812a, and a first connecting portion 813a. Along the first direction, the first connecting portion 813a is located between the first force receiving portion 811a and the force applying portion 812a. The first force receiving portion 811a is exposed through the second hole 1112. In this embodiment, the first force receiving portion 811a is in a shape of a straight bar, and in some embodiments, it may be in a shape of a cross. The first force receiving portion 811a is used to receive an external force. The force applying portion 812a is a protrusion protruding radially. A plurality of force applying portions 812a are provided. In this embodiment, six force applying portions 812a are preferably provided, and the six force applying portions 812a are arranged in sequence along the rotation direction of the energy storage rotating member 81a.

[0490] As Figure 112 and Figure 117 shown, in this embodiment, the energy storage member 83a is preferably a clockwork spring, and in other embodiments, it may be other energy storage components capable of storing power. The energy storage member 83a includes a mounting portion 831a and a second connecting portion 832a. The mounting portion 831a is located at the outer periphery of the energy storage member 83a in the radial direction. The mounting portion 831a is in a shape of a circular hole, and the mounting portion 831a cooperates with the third support column 1114 of the first cover 111 so that the energy storage member 83a is supported by the first cover 111. In some embodiments, the energy storage member 83a may be supported by the cartridge body 10. The second connecting portion 832a is located inside the energy storage member 83a in the radial direction. The second connecting portion 832a cooperates with the first connecting portion 813a so that the energy storage rotating member 81a is connected to the energy storage member 83a. When the energy storage rotating member 81a receives an external force and rotates, the energy storage rotating member 81a causes the energy storage member 83a to rotate or deform through the connection with the energy storage member 83a to store power. In some embodiments, the energy storage rotating member 81a may be integrally formed with the energy storage member 83a.

[0491] As Figures 112 to 119As shown, the force - applying member 82a is generally cylindrical. The force - applying member 82a can be driven by the energy - storing rotating member 81a to rotate. The force - applying member 82a is partially exposed through the third hole 1113 for easy observation. The force - applying member 82a includes a second force - receiving portion 821a. The second force - receiving portion 821a is located at one end of the force - applying member 82a away from the first end 11 along the first direction. The second force - receiving portion 821a is provided in a plurality of numbers, and the plurality of second force - receiving portions 821a are arranged in sequence along the rotation direction of the force - applying member 82a. In this embodiment, the second force - receiving portion 821a is preferably four. The second force - receiving portion 821a is in the shape of an elastic arm and can have a certain elastic deformation ability. The second force - receiving portion 821a can cooperate with the force - applying portion 812a to enable the force - applying member 82a to rotate following the energy - storing rotating member 81a (it is known that the number of the force - applying portions 812a is not less than the number of the second force - receiving portions 821a to facilitate the energy - storing rotating member 81a to drive the force - applying member 82a to rotate). The force - applying member 82a further includes a second supported portion 822a. The second supported portion 822a is preferably a cylinder extending along the first direction. The inside of the second supported portion 822a is hollow, and a first helix 823a is provided therein. The force - applying member 82a further includes a limited projection 824a. The limited projection 824a extends along the first direction. The limited projection 824a is provided in a plurality of numbers, and the plurality of limited projections 824a are arranged at intervals along the rotation direction of the force - applying member 82a. A second surface is provided on the limited projection 824a, and the second surface is an inclined surface or a curved surface. The limited projection 824a is limited by the limiting projection 721a of the limiting member 72a so that the force - applying member 82a cannot rotate. The second surface cooperates with the first surface to facilitate the limiting and releasing of the limiting of the force - applying member 82a by the limiting member 72a.

[0492] As Figure 112 shown, the first end 11 is provided with a mounting member 86. The mounting member 86 includes a fixing portion 861 and a supporting portion 862. In this embodiment, the fixing portion 861 is preferably two. Through holes are provided on the fixing portion 861. The fixing portion 861 cooperates with the second support column 113 of the first end 11, so that the mounting member 86 is mounted on the box body 10. To ensure the stable mounting of the mounting member 86 on the box body 10, the mounting member 86 can be further fixed by screws. In this embodiment, the supporting portion 862 is a hollow cylinder and extends along the first direction. The radius of the supporting portion 862 matches the radius of the second opening 114. The supporting portion 862 is inserted into the second opening 114. To prevent the developer in the box body 10 from leaking, a sealing member can be provided at the connection between the supporting portion 862 and the second opening 114 for sealing. The second supported portion 822a of the force - applying member 82a is inserted into the inside of the supporting portion 862 of the mounting member 86 so that the force - applying member 82a is rotatably supported by the mounting member 86.

[0493] As Figure 120 and Figure 121As shown, the second cover 121 is detachably mounted on the second end 12 of the box body 10. The second cover 121 is provided with lifting protrusions 1216. Preferably, there are two lifting protrusions 1216, which are arranged at intervals in the first direction. In other embodiments, they can be arranged according to actual requirements. The lifting protrusions 1216 are provided with lifting surfaces, which are inclined surfaces or arc surfaces. The lifting surfaces extend leftward in the first direction and upward in the third direction.

[0494] A first support member 87 is detachably provided at the second end 12. The first support member 87 is provided with a first engaging portion 871, and the first engaging portion 871 is in the shape of a guide rail extending in the third direction.

[0495] As Figure 120 and Figure 121 As shown, a second helix 841a is provided at a position where the first transmission rod 84a is close to the first end 11 in the first direction, and the other end is an abutting end 842a. The second helix 841a is supported by the support portion 862 of the mounting member 86 and cooperates with the first helix 823a so that the first transmission rod 84a can be driven by the actuating member 82a to move relative to the box body 10. In this embodiment, preferably, the first transmission rod 84a moves leftward in the first direction. In some embodiments, the first transmission rod 84a can rotate while moving in the first direction. A translating member 85a is provided at the second end 12. The translating member 85a is abutted by the abutting end 842a and moves relative to the box body 10 in the first direction. The translating member 85a moves upward in the third direction along the lifting surface of the lifting protrusion 1216 while moving in the first direction. The translating member 85a is provided with a second engaging portion 851a, and the second engaging portion 851a is in the shape of a protrusion extending in the first direction.

[0496] As Figure 120 and Figure 121 As shown, a third engaging portion 42w, a fourth engaging portion 43w and a triggering portion 41w are provided on the detected member 4w. The third engaging portion 42w is in the shape of a guide rail extending in the first direction. The third engaging portion 42w cooperates with the second engaging portion 851a so that the detected member 4w follows the translating member 85a to move. The fourth engaging portion 43w is in the shape of a protrusion extending in the third direction. The fourth engaging portion 43w cooperates with the first engaging portion 871 so that the detected member 4w moves upward along the extending direction of the first engaging portion 871. The triggering portion 41w directly triggers the detecting member 900. A second elastic member 36w is located at the second end 12. The second elastic member 36w is preferably a compression spring, and can also be other elastic media such as a tension spring or a sponge. The second elastic member 36w interacts with the detected member 4w, and the second elastic member 36w is used to make the detected member 4w move downward.

[0497] The following is the energy storage process and detection process of this embodiment:

[0498] When the energy storage component is installed on the cartridge 10, by applying a force to the first force-receiving portion 811a of the energy storage rotating member 81a, the rotating member rotates in the clockwise direction (in this embodiment, Figure 118 is used as the viewing angle), while the energy storage rotating member 81a rotates, it drives the energy storage member 83a to deform and store power. While the energy storage rotating member 81a rotates to drive the energy storage member 83a to store energy, the force-applying portion 812a interferes with the second force-receiving portion 821a, and the second force-receiving portion 821a deforms to avoid the force-applying portion 812a so that the energy storage rotating member 81a can rotate smoothly in the clockwise direction. During the energy storage process, the force-applying member 82a does not rotate with the energy storage rotating member 81a or only shakes slightly. After the energy storage is completed, the limiting protrusion 721a of the limiting member 72a abuts against the limited protrusion 824a of the force-applying member 82a, and the limiting member 72a prevents the force-applying member 82a from rotating. The end of the second force-receiving portion 821a abuts against the force-applying portion 812a to prevent the energy storage rotating member 81a from rotating counterclockwise when the energy storage member 83a releases power, that is, the limiting member can block the energy storage member 83a from releasing power to prevent the energy storage rotating member 81a from driving the force-applying member 82a to rotate counterclockwise.

[0499] As Figure 122 and Figure 123 shown, when the developing cartridge 1 is installed on the image forming apparatus, before the power output member 920 is inserted into the power receiving portion 211 to output power, the limiting member 72a keeps the force-applying member 82a limited, and the energy storage member 83a remains in the energy storage state. When the power output member 920 is gradually inserted into the power receiving portion 211 in the first direction, the power output member 920 abuts against the force-receiving protrusion 711a of the force-receiving member 71a, causing the force-receiving member 71a to move leftward in the first direction, and further causing the limiting member 72a to move leftward in the first direction. The first elastic member 73a is compressed, the limiting protrusion 721a moves away from the limited protrusion 824a, the limiting member 72a releases the limit on the force-applying member 82a, and the energy storage member 83a can release power. The energy storage rotating member 81a rotates counterclockwise under the action of the power of the energy storage member 83a. The force-applying portion 812a abuts against the end of the second force-receiving portion 821a so that the force-applying member 82a rotates counterclockwise following the energy storage rotating member 81a. When the force-applying member 82a rotates, the first helix 823a acts on the second helix 841a, causing the first transmission rod 84a to be acted on by the force-applying member 82a and move leftward in the first direction. Further, the abutting end 842a of the first transmission rod 84a abuts against the translating member 85a, causing the translating member 85a to move leftward in the first direction and have a movement in the third direction under the action of the lifting protrusion 1216. Further, the translating member 85a drives the detected member 4w to move in the third direction, and the triggering portion 41w triggers the detecting member 900.

[0500] After the detection is completed, the energy storage member 83a releases all its power, and the energy storage rotating member 81a no longer drives the force-applying member 82a to rotate, and the force-applying member 82a no longer drives the first transmission rod 84a to move in the first direction.

[0501] In this embodiment, there is no restriction on the rotation directions of the energy storage rotating member 81a and the force-applying member 82a. During the detection process, the two may rotate clockwise, and when storing energy, the rotating member rotates counterclockwise so that the energy storage member 83a stores energy.

[0502] In some embodiments, after the detection is completed, the energy storage member 83a still continues to release power. However, at this time, the second spiral 841a moves to a position where it does not receive the drive of the first spiral 823a, and the first transmission rod 84a can still stop moving in the first direction.

[0503] It can be known that the linear movement of the force-receiving member 71a in the first direction after being abutted precedes the rotation of the driving part 21 after receiving power. In some embodiments, the movement of the force-receiving member 71a in the first direction can be simultaneous with the rotation of the driving part 21.

[0504] Embodiment Twenty:

[0505] Unless otherwise specified, the structure in this embodiment is the same as that in Embodiment Nineteen.

[0506] The difference between this embodiment and Embodiment Nineteen is that the energy storage assembly is arranged at the second end 12.

[0507] The developing cartridge 1 includes a triggering assembly, an energy storage assembly, and a detected member 4v.

[0508] As Figure 126 and Figure 127 shown, the triggering assembly includes a force-receiving member and a first transmission rod 72. In this embodiment, the force-receiving member and the first transmission rod 72 may be integrally formed or assembled separately. When the force-receiving member is abutted by the power output member and moves, it drives the first transmission rod 72 to move leftward in the first direction to trigger the energy storage assembly. The first transmission rod 72 extends in the first direction, and a triggering protrusion 721 is fixedly arranged on the left end of the first transmission rod 72. The triggering protrusion 721 extends in the radial direction of the first transmission rod 72 and protrudes from the circumferential surface of the first transmission rod 72. In other embodiments, the cross-section of the first transmission rod 72 may also be set as a rectangle or a polygon, and the triggering protrusion 721 may also extend along the second direction or the third direction.

[0509] As Figure 124 shown, in this embodiment, it is preferred that the energy storage assembly is arranged at the second end 12. The energy storage assembly includes a first support member 81, an energy storage member 83, a shield 82, and a locking member 84.

[0510] As Figure 124 and Figure 125As shown, the first support member 81 is fixedly installed on the second end 12. The first support member 81 includes an installation portion and a support portion 811. The installation portion extends along the second direction and is fixedly installed on the second end 12 by means of snap-fastening, screws, etc. The support portion 811 is fixedly arranged with the installation portion, and the support portion 811 and the installation portion may be integrally formed. The support portion 811 extends leftward from the installation portion in the first direction. A first groove 812 is provided on the support portion 811. The first groove 812 is circular. A second support shaft 813 is provided at the center of the first groove 812. A socket 814 is provided on the second support shaft 813. An installation hole 815 extending along the second direction is also provided on the second support shaft 813. A first through hole 8111 is also provided on the support portion 811. The first through hole 8111 extends along the second direction. The first through hole 8111 is located at an eccentric position of the first groove 812. A locking member 84 is installed in the first through hole 8111. The locking member 84 is supported by the first through hole 8111 and can slide relative to the first through hole 8111 in the second direction.

[0511] As Figure 125 and Figure 127 shown, the detected member 4v includes a main body portion and a trigger portion 41v. The main body portion is cylindrical and the main body portion is installed in the first groove 812. The outer circumferential surface of the main body portion is attached to the inner circumferential surface of the first groove 812 and is rotatably supported by the first groove 812. A second groove 42v recessed forward is also formed on the main body portion. The second groove 42v is circular. A third through hole 44v is provided on the main body portion. The third through hole 44v extends along the second direction. As the detected member 4v rotates, the third through hole 44v can rotate to a position aligned with the first through hole 8111 in the second direction. A pushing inclined surface 45v is provided at the upstream end of the third through hole 44v in the rotation direction of the detected member 4v. The inclination direction of the pushing inclined surface 45v is set such that the upstream end in the rotation direction of the detected member 4v is more forward in the second direction than the downstream end. The pushing inclined surface 45v is used to contact the locking member 84 and apply a pushing force to the locking member 84 that has a forward component force in the second direction.

[0512] The trigger portion 41v is fixedly arranged on the outer circumferential surface of the main body portion. Specifically, the trigger portion 41v is integrally formed on the outer circumferential surface of the main body portion and extends radially in a direction away from the axis of the main body portion. A second through hole 43v for the second support shaft 813 to pass through is formed on the main body portion.

[0513] The energy storage member 83 is a coil spring or a clockwork spring. In this embodiment, it is preferably a coil spring. One end of the coil spring is inserted into the socket 814 and thus fixed by the socket 814. The other end of the coil spring is fixedly connected to the inner circumferential surface of the second groove 42v of the detected member 4v.

[0514] As Figure 125 and Figure 127As shown, the shield 82 is disc-shaped. An installation post 821 is provided at the front end of the shield 82. The installation post 821 is inserted into the installation hole 815 so that the shield 82 is fixedly installed on the first support member 81. The shield 82 is used to cover the first groove 812 and the second groove 42v, preventing external objects from touching the energy storage member 83 and having a limiting effect on the energy storage member 83 and the detected member 4v, preventing the energy storage member 83 from disengaging from the second groove 42v backward and preventing the detected member 4v from disengaging from the first groove 812 backward.

[0515] The energy storage assembly has a holding state and a release state. When the developing cartridge 1 leaves the factory, it is uniformly preset to be in the holding state. When the energy storage assembly is in the holding state, the energy storage member 83 undergoes elastic deformation and stores elastic potential energy. The locking member 84 is simultaneously inserted into the first through hole 8111 and the third through hole 44v, and the locking member 84 is abutted by the triggering protrusion 721 to counteract the pushing force applied to the locking member 84 by the pushing inclined surface 45v, so that the locking member 84 cannot disengage from the first through hole 8111, thereby restricting the rotational movement of the detected member 4v under the elastic force of the energy storage member 83 and keeping it stationary. That is, in this embodiment, the locking member 84 acts as a limiting member to limit the detected member 4v to prevent the detected member 4v from moving within a non-predetermined time.

[0516] When the energy storage assembly is in the release state, the locking member 84 is disengaged from contact with the triggering protrusion 721. Under the elastic force of the energy storage member 83, the detected member 4v receives an elastic force in the circumferential direction, so that the detected member 4v applies a pushing force to the locking member 84 through the pushing inclined surface 45v, causing the locking member 84 to move forward and disengage from the third through hole 44v, and no longer limiting the detected member 4v, so that the detected member 4v can rotate under the elastic force of the energy storage member 83.

[0517] When the first transmission rod 72 moves in the first direction following the force-receiving member, the triggering protrusion 721 moves leftward from the untriggered position to the triggered position together with the first transmission rod 72. When the triggering protrusion 721 is in the untriggered position, it abuts against the locking member 84 and applies a backward acting force to the locking member 84, so that the locking member 84 is held in the first through hole 8111 and the third through hole 44v, thereby restricting the rotation of the detected member 4v, that is, keeping the energy storage assembly in the holding state. After the triggering protrusion 721 moves to the triggered position, the triggering protrusion 721 is disengaged from abutting against the locking member 84, and the energy storage assembly enters the release state, and the locking member 84 disengages from the third through hole 44v and no longer limits the detected member 4v.

[0518] After the energy storage component enters the release state, the detected part 4v rotates counterclockwise (observed from back to front) under the elastic force of the energy storage part 83, so that the triggering part 41v makes a circular motion counterclockwise, and then contacts the detection part and drives the detection part to move, thereby triggering the detection part. In the present application, the developing cartridge 1 can change the number of rotations of the detected part 4v by changing the energy storage degree of the energy storage part 83 or change the number of triggering parts 41v, so as to change the number of trigger times of the triggering part 41v triggering the detection part. By selecting energy storage parts 83 of different specifications or changing the size of the triggering part 41v in the rotation direction, the triggering duration and triggering speed when the triggering part 41v triggers the detection part can be changed.

[0519] This embodiment provides a developing cartridge 1, which can provide a new structure for the developing cartridge 1 to be detected by an image forming apparatus. It does not need to be powered by the image forming apparatus to operate. Only the image forming apparatus needs to trigger the trigger part at the initial stage, and then it can operate by the power stored in the energy storage component. Compared with the prior art, the load on the power output part of the image forming apparatus is reduced, which is beneficial to extending the service life of the image forming apparatus.

[0520] Embodiment XXI:

[0521] Unless otherwise specified, the structure in this embodiment is the same as that in Embodiment XIX.

[0522] The difference between this embodiment and Embodiment XIX lies in: the energy storage components are different.

[0523] As Figures 128 - 131 shown, in this embodiment, the energy storage component includes an energy storage part 83a, a translation part 85a, a first transmission rod 84b, and a second transmission rod 86b. The translation part 85a is the same as that in Embodiment XX, and will not be described in detail in this embodiment.

[0524] As Figures 128 - 131 shown, in this embodiment, the energy storage part 83b is preferably a torsion spring, and the energy storage part 83b is in an energy storage state when installed on the cartridge body 10. The energy storage part 83b includes a second force application part 831b.

[0525] As Figures 128 - 131As shown, a limiting protrusion 841b and a fourth abutting protrusion 842b are provided on the first transmission rod 84b. The limiting protrusion 841b protrudes radially from the first transmission rod 84b and is limited by the limiting protrusion 721a so that the first transmission rod 84b cannot rotate. The fourth abutting protrusion 842b protrudes radially from the first transmission rod 84b. The energy storage member 83b is sleeved on the first transmission rod 84b, and the second force application portion 831b abuts against the limiting protrusion 841b. The right end of the first transmission rod 84b can extend out of the fourth hole of the first cover 111. Workers can rotate the first transmission rod 84b during factory presetting to twist and store energy in the energy storage member 83b, and then limit the first transmission rod 84b through the limiting member 72a. When the limiting member 72a releases the limit on the first transmission rod 84b, the energy storage member 83b releases power so that the first transmission rod 84b rotates relative to the box body 10.

[0526] As Figure 130 shown, an abutted portion 1115 is provided on the first cover 111. The abutted portion 1115 surrounds the fourth hole and is spiral and extends in the direction close to the first end 11. The fourth abutting protrusion 842b of the first transmission rod 84b abuts against the abutted portion 1115. When the first transmission rod 84b is driven to rotate by the energy storage member 83b, the fourth abutting protrusion 842b is affected by the abutted portion 1115 and drives the first transmission rod 84b to move leftward in a rotating manner along the first direction.

[0527] As Figure 131 shown, in this embodiment, a second transmission rod 86b is further provided. One end of the second transmission rod 86b abuts against the left end of the first transmission rod 84b, and the other end abuts against the translation member 85a. When the first transmission rod 84b moves leftward along the first direction, it drives the second transmission rod 86b to move leftward along the first direction. The second transmission rod 86b drives the translation member 85a to move along the first direction, thereby causing the detected member 4w to move and trigger the detector 900. That is, in this embodiment, the first transmission rod 84b only makes a linear motion without rotating. In some embodiments, only the first transmission rod 84b can be provided, and the first transmission rod 84b drives the translation member 85a to move.

[0528] Embodiment Twenty-two:

[0529] Without special instructions, the structure in this embodiment is the same as the structure in Embodiment Nineteen.

[0530] The difference between this embodiment and Embodiment Nineteen lies in: the energy storage assembly and the triggering assembly are different.

[0531] As Figure 132 and Figure 133As shown, in this embodiment, the triggering assembly includes a force-receiving member 71a, a first restricting member 72c, and a second restricting member 73c. The energy storage assembly includes a first transmission rod 84c, a receiving member 87c, an energy storage member 83c, and a translation member 85a. The force-receiving member 71a and the translation member 85a are the same as those in Embodiment 20 and will not be elaborated here. The first restricting member 72c is abutted by the force-receiving member 71a. When the force-receiving member 71a is stressed and moves in the first direction, the first restricting member 72c follows the force-receiving member 71a and moves leftward in the first direction. A force-applying surface 721c is provided at one end of the first restricting member 72c that is away from the force-receiving member 71a in the first direction. The force-applying surface 721c is an arc surface or an inclined surface, and its extending direction intersects with the first direction and the second direction. Specifically, it extends leftward in the first direction and backward in the second direction. The second restricting member 73c includes a force-receiving hole 731c and a second limiting portion 732c. The force-receiving hole 731c is connected to the first restricting member 72c. Specifically, the force-applying surface 721c is inserted into the force-receiving hole 731c. When the first restricting member 72c moves leftward in the first direction, the force-applying surface 721c is further inserted into the force-receiving hole 731c, thereby driving the second restricting member 73c to move forward in the second direction. The second limiting portion 732c is a protrusion at one end of the second restricting member 73c that is away from the developing roller 131 in the second direction.

[0532] As Figure 132 and Figure 133 shown, one end of the first transmission rod 84c in the first direction is a force-receiving end, and the other end is an abutting end. A third force-receiving portion 841c, a restricted portion 842c, and an air outlet hole 843c are provided on the force-receiving end. The third force-receiving portion 841c is a hole-shaped recess along the first direction. The restricted portion 842c is a groove recessed in the radial direction of the force-receiving end. The air outlet hole 843c is a through hole in the radial direction of the first transmission rod 84c. The second limiting portion 732c of the second restricting member 73c is inserted into the restricted portion 842c. The second restricting member 73c is used to restrict the movement of the first transmission rod 84c, and further to limit the movement of the first transmission rod 84c in the first direction. The receiving member 87c is a container with good airtightness, and gas is stored therein. The force-receiving end is movably received in the receiving member 87c, and the air outlet hole 843c is surrounded by the receiving member 87c and communicates with the outside.

[0533] As Figure 132 and Figure 133 shown, in this embodiment, the energy storage member 83c is preferably a compression spring, which has an elastic force after deformation. One end of the energy storage member 83c close to the first end 11 in the first direction is installed in the third force-receiving portion 841c of the first transmission rod 84c, and the other end abuts against the cover 111. The energy storage member 83c applies an elastic force to the first transmission rod 84c so that the first transmission rod 84c can move leftward in the first direction.

[0534] After the developing cartridge 1 is assembled, the energy storage member 83c is in an energy storage state, that is, it has an elastic force and applies a force to move the first transmission rod 84c in the first direction. The second limiting portion 732c is inserted into the limited portion 842c, that is, the second limiting member 73c restricts the movement of the first transmission rod 84c in the first direction. When the force-receiving member 71a moves leftward in the first direction, the first limiting member 72c drives the second limiting member 73c to move forward in the second direction, and the second limiting member 73c releases the restriction on the first transmission rod 84c. The first transmission rod 84c moves leftward in the first direction under the action of the energy storage member 83c.

[0535] During the process of the first transmission rod 84c moving leftward in the first direction, the gas in the accommodating member 87c gradually discharges through the air outlet hole 843c. In this embodiment, the speed of the first transmission rod 84c moving in the first direction is controlled by gradually discharging the gas in the accommodating member 87c during the movement of the first transmission rod 84c, so as to avoid the uncontrollable movement speed of the first transmission rod 84c under the action of the energy storage member 83c. By designing the size of the air outlet hole 843c, the speed of the discharged gas is determined, and further the speed of the first transmission rod 84c moving is controlled.

[0536] Embodiment Twenty-three:

[0537] Unless otherwise specified, the structure in this embodiment is the same as that in Embodiment Twenty-two.

[0538] The difference between this embodiment and Embodiment Twenty-two lies in: different energy storage components.

[0539] As Figure 134 and Figure 135 shown, the energy storage component in this embodiment includes a first support member 81d and an energy storage member 83d. The triggering component is the same as that in Embodiment Twenty-two and will not be elaborated here.

[0540] In this embodiment, the energy storage member 83d is a constant force spring, which always has a contracting elastic force. The energy storage member 83d includes a main body portion 831d and a first fixing hole 832d. The main body portion 831d is cylindrical, and the main body portion 831d always has a tendency to contract. It is hollow and extends along the second direction inside. The first fixing hole 832d is a through hole at the end of the energy storage member 83d. The first support member 81d is used to support the energy storage member 83d. The first support member 81d is inserted into the inside of the main body portion 831d of the energy storage member 83d to support the energy storage member 83d. The energy storage member 61 can drive the first support member 81d to move along the first direction. A fourth guide rail 1116 is provided on the first cover 111. The fourth guide rail 1116 extends along the first direction, and the first support member 81d is movably supported by the fourth guide rail 1116. A limited protrusion 811d is provided on the first support member 81d. The limited protrusion 811d is abutted by the second limiting portion 732c to limit the movement of the first support member 81d along the first direction, thereby limiting the contraction of the energy storage member 83d.

[0541] To control the contraction of the main body portion 831d in a preset direction, a fixing member 82d is provided and inserted into the first fixing hole 832d of the energy storage member 83d, so that the main body portion 831d contracts in the direction close to the first fixing hole 832d. A second fixing hole 1117 is provided on the first cover 111. The fixing member 82d is inserted into the first fixing hole 832d and the second fixing hole 1117 at the same time, so that the energy storage member 83d is further supported by the first cover 111. In some embodiments, the second fixing hole may be provided on the box body 10.

[0542] The side surface of the main body portion 831d of the energy storage member 83d abuts against the first transmission rod 84d. When the second limiting portion 732c releases the limitation on the first support member 81d, the energy storage member 83d contracts. The main body portion 831d drives the first support member 81d to move leftward along the first direction. The main body portion 831d abuts against the first transmission rod 84d, causing the first transmission rod 84d to move leftward along the first direction.

[0543] Embodiment Twenty-four:

[0544] Unless otherwise specified, the structure in this embodiment is the same as the structure in Embodiment Nineteen.

[0545] The difference between this embodiment and Embodiment Nineteen is that: a speed control component is also provided in this embodiment.

[0546] Such as Figures 136 - 140As shown, to prevent the energy storage rotating member 81a from rotating too fast when the energy storage member 83a releases power, which may cause the moving speeds of the force applying member 82a and the first transmission rod 84a to be too fast and affect the triggering of the detection member 900 by the detected member 4w, in this embodiment, a control assembly is provided to control the rotation speeds of the force applying member 82a and the energy storage rotating member 81a, so as to control the speed of the first transmission rod 84a. The speed control assembly in this embodiment is preferably an escapement system, and the speed control assembly includes an escapement fork 301 and an escapement wheel 302.

[0547] As Figures 136 - 140 shown, a support platform 86e is provided at the first end 11. The support platform 86e is clamped to the first cover 111 or the box body 10 by clamping. The support platform 86e includes a support rod 861e, and the support rod 861e is a round rod extending in the first direction. The escapement fork 301 includes a first convex portion 3011, a second convex portion 3012, a clamped portion 3013, and a hole portion 3014. The hole portion 3014 is preferably a round hole, and the hole portion 3104 cooperates with the support rod 861e, that is, the support rod 861e is inserted into the hole portion 3014 so that the escapement fork 301 is rotatably supported by the support rod 861e. A second clamping portion 1118 is provided on the first cover 111, and the clamped portion 3013 is clamped by the second clamping portion 1118. The clamped portion 3013 has a certain elasticity. The first convex portion 3011 and the second convex portion 3012 are located on the rotation path of the escapement wheel 302, and the first convex portion 3011 and the second convex portion 3012 come into contact with the escapement wheel 302 successively to reduce the rotation speed of the escapement wheel 302. Radially, the first convex portion 3011 and the second convex portion 3012 are located on one side of the hole portion 3014, and the clamped portion 3013 is located on the other side of the hole portion 3014. When the first convex portion 3011 and the second convex portion 3012 are abutted by the escapement wheel 302 and cause the escapement fork 301 to rotate around the hole portion 3014 as a rotation point, the clamped portion 3013 generates elastic deformation, and elastically recovers after the first convex portion 3011 and the second convex portion 3012 lose the abutment, so that the escapement fork 301 rotates in the reverse direction to reset.

[0548] As Figures 136 - 140As shown, the escapement wheel 302 and the force - applying member 82a rotate coaxially and in the same direction. The escapement wheel 302 is driven by the energy - storing rotating member 81a to rotate. The escapement wheel 302 includes an abutting convex portion 3021 and a fourth force - receiving portion 3022. The radius of the abutting convex portion 3021 is greater than the radius of the fourth force - receiving portion 3022, that is, in the radial direction, the fourth force - receiving portion 3022 is located inside the abutting convex portion 3021. The abutting convex portion 3021 is a protrusion protruding radially with respect to the escapement wheel 302, and the protruding direction of the abutting convex portion 3021 intersects both the radial direction and the rotation direction. A plurality of abutting convex portions 3021 are provided, and the plurality of abutting convex portions 3021 are arranged at intervals along the rotation direction of the escapement wheel 302. When the escapement wheel 302 rotates, the first convex portion 3011 and the second convex portion 3012 of the escapement fork 301 abut against the abutting convex portion 3021 and elastically yield to reduce the rotation speed of the escapement wheel 302. The fourth force - receiving portion 3022 is used to be driven by the energy - storing rotating member 81a so that the escapement wheel 302 rotates following the energy - storing rotating member 81a. A plurality of fourth force - receiving portions 3022 are provided, and the plurality of fourth force - receiving portions 3022 are arranged along the rotation direction of the escapement wheel 302. In this embodiment, the fourth force - receiving portion 3022 is preferably a wedge - shaped structure, which includes a force - receiving surface and a passing - over surface. The force - receiving surface and the passing - over surface intersect each other. When the energy - storing rotating member 81a stores energy and rotates, the force - applying portion 812a of the energy - storing rotating member 81a contacts the passing - over surface but does not drive the escapement wheel 302 to rotate. When the energy - storing rotating member 81a releases rotation, the force - applying portion 812a abuts against the force - receiving surface, so that the escapement wheel 302 rotates following the energy - storing rotating member 81a. In this embodiment, the structure of the second force - receiving portion 821a of the force - applying member 82a is the same as that of the fourth force - receiving portion 3022.

[0549] In this embodiment, the energy - storing rotating member 81a rotates counter - clockwise (in this embodiment, taking Figure 139 as the perspective) to store energy in the energy - storing member 83a. When the energy - storing member 83a releases power, the rotating member rotates clockwise and drives the force - applying member 82a and the escapement wheel 302 to rotate clockwise. When the escapement wheel 302 rotates, the abutting convex portion 3021 abuts against the first convex portion 3011 and the second convex portion 3012 successively. The escapement wheel 302 applies a swinging force to the escapement fork 301, and the escapement fork 301 applies a reaction force to the escapement wheel 302. This reaction force reduces the rotation speed of the escapement wheel 302, thereby reducing the rotation speed of the energy - storing rotating member 81a, and further reducing the rotation speed of the force - applying member 82a. Therefore, the speed of the first transmission rod 84a moving leftward in the first direction is reduced.

[0550] In this embodiment, the escapement fork 301 elastically avoids the escapement wheel 302 after being abutted by the escapement wheel 302, which not only reduces the rotation speed of the escapement wheel 302, but also prevents the escapement wheel 302 from being completely stuck and unable to rotate. In other embodiments, the clamped portion 3013 may not be provided, and a connecting portion may be provided on the other side of the hole portion 3014 along the radial direction. The connecting portion is connected to an elastic member. When the escapement fork 301 is abutted and rotated, the elastic member is deformed. When the escapement fork 301 loses the abutment, the elastic member elastically recovers, causing the escapement fork 301 to rotate in the opposite direction to reset.

[0551] In other embodiments, the speed control component is a hairspring type, which can also reduce the rotation speed of the energy storage rotating member 81a and thus reduce the rotation speed of the force applying member 82a and the translation speed of the first transmission rod 84a.

[0552] In some embodiments, the speed control component is grease, preferably damping oil, which has high stability and viscosity. The damping oil is applied to the first spiral 823a and the second spiral 841a, which can not only reduce the friction between the first spiral 823a and the second spiral 841a to play a protective role, but also reduce the translational speed of the first transmission rod 84a.

[0553] In other embodiments, damping oil is applied to the pallet fork 301 to slow down the rotational avoidance speed of the pallet fork 301 , thereby further slowing down the rotational speed of the escape wheel 302 .

[0554] like Figure 141 As shown, in some embodiments, the other side of the hole portion 3014 in the radial direction is a pendulum 3015. When the developing box 1 is installed in the image forming device, the pendulum 3015 swings, and after the first protrusion 3011 and the second protrusion 3012 lose abutment, the pendulum 3015 swings to reset the escapement fork 301.

[0555] Embodiment 25:

[0556] Unless otherwise specified, the structure in this embodiment is the same as that in Embodiment 24.

[0557] The difference between this embodiment and embodiment twenty-four is that the structure of the speed control component in this embodiment is different, and the transmission rod directly triggers the detection member 900.

[0558] like Figure 142 and Figure 143As shown, in this embodiment, a first gear portion 825f is further provided on the force applying member 82f, and a first gear 88f and a second gear 89f are further provided at the first end 11. The first gear 88f and the second gear 89f are rotatably supported by the housing 10. The first gear 88f meshes with the first gear portion 825f to rotate following the force applying member 82f, and the second gear 89f meshes with the first gear 88f to rotate following the first gear 88f. The transmission rotating member 39f receives the power transmitted by the second gear 89f and rotates to drive the detected member to move.

[0559] As Figure 142 and Figure 143 As shown, in this embodiment, the speed control assembly includes a first abutted member 303 and a first deceleration elastic member 304. The first abutted member 303 is movably supported by the housing 10. The first abutted member 303 can move relative to the housing 10 in a first direction. The first abutted member 303 includes a first abutted surface 3031, and the first abutted surface 3031 is preferably an inclined surface or a curved surface. The extending direction of the first abutted surface 3031 intersects with the first direction. In the first direction, the first deceleration elastic member 304 is located between the first abutted member 303 and the first end 11. The first deceleration elastic member 304 can be compressed and extended along the first direction. The first deceleration elastic member 304 provides an elastic force for the first abutted member 303 to move rightward in the first direction. The first deceleration elastic member 304 and the first abutted member 303 are preferably two groups. When the force applying member 82f rotates, the limited protrusion 824a of the force applying member 82f abuts against the first abutted member 303, and further, the second surface (inclined surface) abuts against the first abutted surface 3031. The first abutted member 303 receives a force to the left in the first direction applied by the force applying member 82f. The first abutted member 303 applies a reaction force to the force applying member 82f to reduce the rotation speed of the force applying member 82f, and the first deceleration elastic member 304 is compressed. After the force applying member 82f continues to rotate, the limited protrusion 824a passes over the first abutted member 303, and the first deceleration elastic member 304 applies an elastic force to the first abutted member 303 to make it move rightward in the first direction, so that the first abutted member 303 is abutted by the remaining limited protrusions 824a again.

[0560] As Figure 142 and Figure 143As shown, the speed control component further includes a second abutting member 305 and a second decelerating elastic member 306. The second abutting member 305 can move relative to the box body 10 in the first direction. In the first direction, the second decelerating elastic member 306 is located between the second abutting member 305 and the first cover 111, and the second decelerating elastic member 306 can be compressed and extended in the first direction. A second abutting surface 3051 is provided on the second abutting member 305. Preferably, there are multiple second abutting surfaces 3051, and the multiple second abutting surfaces 3051 are arranged along the rotation direction of the second gear 89f. The second abutting surface 3051 is preferably an inclined surface or an arc surface, and the extending direction of the second abutting surface 3051 intersects with the first direction and the radial direction. A third abutting surface 891f is provided on the second gear 89f. Preferably, there are multiple third abutting surfaces 891f, and the multiple third abutting surfaces 891f are arranged along the rotation direction of the second gear 89f. The third abutting surface 891f is preferably an inclined surface or an arc surface, and the extending direction of the third abutting surface 891f intersects with the first direction and the radial direction. The extending direction of the third abutting surface 891f intersects with the extending direction of the second abutting surface 3051, and the two are arranged in a matching manner. When the second gear 89f rotates, the second abutting surface 3051 abuts against the third abutting surface 891f, and the third abutting surface 891f exerts a force on the second abutting surface 3051 to move the second abutting member 305 to the right in the first direction, so that the second decelerating elastic member 306 is compressed. The second abutting member 305 exerts a reaction force on the second gear 89f, and this reaction force reduces the rotation speed of the second gear 89f, and further reduces the rotation speed of the transmission rotating member 39f, thereby reducing the movement of the detected member. The second decelerating elastic member 306 releases the elastic force to move the second abutting member 305 to the left in the first direction to exert a reaction force on the second gear 89f again. In some embodiments, only the first abutting member 303 may be provided.

[0561] It can be known that in this embodiment, the power can also be transmitted from the first end 11 to the second end 12 by using a flexible member or multiple rotating members.

[0562] It can be known that the second abutting member 305 can act on the first gear 88f.

[0563] It can be known that the second gear portion 395f of the transmission rotating member 39f can be a toothless portion to prevent the energy storage member 83a from continuously releasing power after the detection is completed.

[0564] Embodiment Twenty-Six:

[0565] Without special instructions, the structure in this embodiment is the same as the structure in Embodiment Nineteen.

[0566] Such as Figures 144 to 146As shown, the difference between this embodiment and the nineteenth embodiment is that the energy storage component is cancelled, and a transmission component is provided to drive the detected part 4w.

[0567] In this embodiment, a transmission protrusion 251w protruding leftward is provided on the left end surface of the first idler wheel 25w. The transmission protrusion 251w extends circumferentially around the rotation axis of the first idler wheel 25w. A transmission inclined surface 2511w is provided on the transmission protrusion 251w. The inclination direction of the transmission inclined surface 2511w is set such that the upstream end of the transmission inclined surface 2511w is more to the left in the first direction than the downstream end in the rotation direction of the first idler wheel 25w.

[0568] This embodiment further includes a transmission component, which includes a pipe fitting 31w and a ball 32w.

[0569] The pipe fitting 31w is fixedly provided on the box body 10. The pipe fitting 31w extends in the first direction. The right end of the pipe fitting 31w is located at the first end 11, and the left end is located at the second end 12. In this embodiment, the pipe fitting 31w penetrates through the accommodating cavity of the box body 10 in the first direction and is provided on the box body 10. In other embodiments, the pipe fitting 31w can also be provided on the outer surface of the box body 10. The pipe fitting 31w can also be integrally formed with the box body 10, or a part of the pipe fitting 31w is integrally formed with the box body 10 and the other part is fixedly connected to the box body 10 in a split manner, and the two parts of the pipe fitting 31w are combined into a complete pipe fitting 31w.

[0570] A notch 311w for the transmission protrusion 251w to pass through is provided on the side wall of the part of the pipe fitting 31w located at the first end 11. The transmission protrusion 251w is inserted into the notch 311w from right to left and can rotate relative to the notch 311w. A plurality of mutually contacting balls 32w are arranged in sequence in the pipe fitting 31w from the first end 11 to the second end 12 along the first direction and can slide and roll along the pipe fitting 31w relative to the pipe fitting 31w.

[0571] The projections of the translating member 85a, the third mating portion 42w, and the pipe fitting 31w in the first direction coincide, so that when the ball 32w moves along the pipe fitting 31w in the first direction, it can push the translating member 85a to move leftward along the third mating portion 42w in the first direction.

[0572] When the driving part 21 rotates upon receiving the power of the image forming apparatus, it drives the first idler wheel 25w to rotate. The transmission inclined plane 2511w on the first idler wheel 25w rotates together with the first idler wheel 25w, thereby applying a leftward acting force in the first direction to the ball 32w within the pipe fitting 31w, causing the ball 32w to move leftward. The ball 32w then pushes the translating member 85a leftward along the third mating portion 42w within the pipe fitting 31w. When the translating member 85a passes through the lifting protrusion 1216, it moves upward in the third direction under the acting force provided by the lifting protrusion 1216, thereby driving the detected member 4w to move upward from the non-detection position to the detection position, thus triggering the detection member. The reset elastic member 36w causes the detected member 4w to move downward from the detection position to the non-detection position.

[0573] Embodiment Twenty-Seven:

[0574] Unless otherwise specified, the structure in this embodiment is the same as that in Embodiment Twenty.

[0575] As Figures 147 to 149 shown, the difference between this embodiment and Embodiment Twenty is that the energy storage component is cancelled, and a first on-off component, a second on-off component, and a power source are also provided.

[0576] The first on-off component includes the following structure. A guiding ring 33v is arranged within the first support column 101. A guiding groove 331v extending in the first direction is arranged on the guiding ring 33v. The guiding groove 331v is a through groove evenly distributed on the outer circumferential surface of the guiding ring 33v along the circumferential direction. A first electrical contact 34v is arranged at the left end of the guiding ring 33v. A second electrical contact 32v is arranged on the right side of the guiding ring 33v. A guiding protrusion 321v corresponding to the guiding groove 331v one by one is arranged on the second electrical contact 32v. The guiding protrusion 321v extends leftward from the second electrical contact 32v. The guiding protrusion 321v is in sliding fit with the guiding groove 331v. The right end of the second electrical contact 32v is fixedly connected to the left end of the force receiving member 71v. A first opening 1012 is arranged on the side wall of the first support column 101. The first electrical contact 34v is connected to a first wire 37v. The second electrical contact 32v is connected to a second wire 38v. The first wire 37v and the second wire 38v extend outside the first support column 101 through the first opening 1012.

[0577] When the triggering component is in the untriggered position, the guiding protrusion 321v on the second electrical contact 32v is in the first disconnected position where it is not in contact with and not electrically connected to the first electrical contact 34v. When the triggering component is in the triggered state, the second electrical contact 32v moves leftward together with the force receiving member 71v, so that the guiding protrusion 321v moves leftward along the guiding groove 331v to the first connected position where it is in contact with and electrically connected to the first electrical contact 34v.

[0578] The second on-off component includes the following structure. The first end 11 is further provided with a third electrical contact 35v and a fourth electrical contact 36v. The first end 11 is provided with a first cylinder 37v for supporting the third electrical contact 35v and the fourth electrical contact 36v. Both the third electrical contact 35v and the fourth electrical contact 36v are in the shape of a hollow ring. The third electrical contact 35v and the fourth electrical contact 36v are sleeved on the outer surface of the first cylinder 37v and can slide along the first cylinder 37v in the first direction. In this embodiment, the third electrical contact 35v and the fourth electrical contact 36v are coaxially arranged with the stirring gear 24v. The left end of the stirring gear 24v passes through the first cylinder 37v and extends into the accommodation cavity to be fixedly connected with the stirring frame. That is, the first cylinder 37v is in the shape of a hollow circular tube. The stirring gear 24v is rotatably supported by the inner circumferential surface of the first cylinder 37v. The third electrical contact 35v and the fourth electrical contact 36v are supported by the outer circumferential surface of the first cylinder 37v. The outer circumferential surface of the first cylinder 37v is further provided with a limiting rib 371v protruding in the direction away from the rotation axis of the first cylinder 37v along the radial direction. The third electrical contact 35v and the fourth electrical contact 36v are provided with limiting grooves for inserting the limiting rib 371v. Through the cooperation of the limiting rib 371v and the limiting grooves, the third electrical contact 35v and the fourth electrical contact 36v are limited in the circumferential direction and cannot rotate. At the same time, the limiting rib 371v extends along the first direction to guide the third electrical contact 35v and the fourth electrical contact 36v to move in the first direction. The fourth electrical contact 36v is located on the left side of the third electrical contact 35v. The stirring gear 24v includes a gear shaft 241v and a gear portion fixedly connected. The gear shaft 241v extends leftward from the left end surface of the gear portion and is inserted into the first cylinder 37v to be rotatably supported by the first cylinder 37v. The gear shaft 241v is also fixedly connected with the stirring frame. The gear portion is located outside the first cylinder 37v and on the right side of the third electrical contact 35v. The circumferential surface of the gear shaft 241v is provided with a make-and-break protrusion 242v. The make-and-break protrusion 242v protrudes in the direction away from the rotation axis of the gear shaft 241v along the radial direction of the gear shaft 241v.An on-off abutting protrusion 361v protruding rightward is fixedly arranged at an eccentric position on the right end face of the fourth electrical contact 36v. An avoidance notch 351v for inserting the on-off abutting protrusion 361v is arranged on the third electrical contact 35v. The right end of the on-off abutting protrusion 361v extends rightward out of the avoidance notch 351v and is located on the right side of the third electrical contact 35v. An on-off abutting inclined surface 362v is arranged on the on-off abutting protrusion 361v. The inclination direction of the on-off abutting inclined surface 362v is set such that the upstream end of the on-off abutting inclined surface 362v is more to the left than the downstream end in the rotation direction of the stirring gear 24v. The on-off abutting inclined surface 362v is used to contact the on-off protrusion 242v so as to receive the acting force provided by the on-off protrusion 242v and drive the fourth electrical contact 36v to move leftward from the second connection position in contact with and electrically connected to the third electrical contact 35v to the second disconnection position not in contact with and disconnected from the third electrical contact 35v. When the developing cartridge is in the factory preset state, the third electrical contact 35v and the fourth electrical contact 36v are in the second connection position.

[0579] One end of the first wire 37v is fixedly connected and electrically connected to the second electrical contact 32v, and the other end is fixedly connected and electrically connected to the third electrical contact 35v. A third wire 39v is fixedly connected and electrically connected to the fourth electrical contact 36v.

[0580] The power source is fixedly arranged at the second end 12. The power source is a motor 31v. A battery electrically connected to and supplying power to the motor 31v is fixedly installed on the motor 31v. One end of the second wire 38v is fixedly connected and electrically connected to the first electrical contact 34v, and the other end is fixedly connected and electrically connected to the positive terminal of the motor 31v. One end of the third wire 39v is fixedly connected and electrically connected to the fourth electrical contact 36v, and the other end is fixedly connected and electrically connected to the negative terminal of the motor 31v. The second wire 38v and the third wire 39v extend from the first end 11 to the second end 12.

[0581] The motor 31v is fixedly arranged at the rear end of the first support member 81v. The motor output shaft passes through the first support member 81v and extends to the front end of the first support member 81v and is fixedly connected to the detected member 4v to transmit power to the detected member 4v, so that the detected member 4v rotates around an axis extending in the second direction.

[0582] The specific working process is as follows:

[0583] When the developing cartridge is installed in the image forming apparatus and the power output member in the image forming apparatus starts to rotate, the driving trigger assembly moves from the non-triggered position to the triggered position, so that the force-receiving member 71v drives the second electrical contact member 32v and the guiding protrusion 321v to move leftward, so that the guiding protrusion 321v contacts and is electrically connected to the first electrical contact member 34v and moves from the first disconnected position to the first connected position. At this time, the motor 31v and the battery form a circuit, and the battery supplies power to the motor 31v, so that the motor 31v starts to drive the detected member 4v to rotate. The triggering portion 41v on the detected member 4v drives and triggers the detecting member as the detected member 4v rotates, so that the image forming apparatus detects the developing cartridge.

[0584] Then, as the driving portion 21 rotates upon receiving the power provided by the power output member of the image forming apparatus, the power of the driving portion 21 is transmitted to the stirring gear 24v, so that the stirring gear 24v rotates. The stirring gear 24v drives the on-off protrusion 242v to rotate, so that the on-off protrusion 242v rotates to a position where it contacts the on-off abutting slope 362v on the on-off abutting protrusion 361v and applies a force to the on-off abutting slope 362v. After the on-off abutting slope 362v receives a force with a leftward component force, it drives the fourth electrical contact member 36v to move leftward from the second connected position where it contacts the third electrical contact member 35v to the second disconnected position where it disengages from the third electrical contact member 35v and disconnects the electrical connection, so that an open circuit is formed between the motor 31v and the battery, and the battery can no longer supply power to the motor 31v. At this time, the detected member 4v stops rotating without power input, and the detection process is completed.

[0585] Embodiment Twenty-Eight:

[0586] Unless otherwise specified, the structure in this embodiment is the same as the structure in Embodiment Twenty-Six.

[0587] As Figures 150 to 153 shown, the difference between this embodiment and Embodiment Twenty-Six is that the pipe fitting, the ball, and the translation member are cancelled.

[0588] An on-off assembly and an electromagnet assembly are further provided in this embodiment.

[0589] The electromagnet assembly includes an electromagnet 44x, a swinging member 42x, and a battery 45x. A first wire 31x is provided between the positive electrode of the battery 45x and the positive electrode of the electromagnet 44x. One end of the first wire 31x is fixedly connected and electrically connected to the positive electrode of the battery 45x, and the other end is fixedly connected and electrically connected to the positive electrode of the electromagnet 44x. The negative electrode of the electromagnet 44x is fixedly connected and electrically connected to a second wire 32x, and the negative electrode of the battery 45x is fixedly connected and electrically connected to a third wire. The second wire 32x and the third wire extend into the accommodation chamber. The stirring frame and the stirring gear 24x are provided with a wire mounting hole penetrating the stirring frame and the stirring gear 24x in a first direction. The second wire 32x and the third wire are arranged in the wire mounting hole and extend from the second end 12 to the first end 11 along the wire mounting hole and extend out of the wire mounting hole to the right.

[0590] The swinging member 42x is rotatably mounted on the first support member 81x and the swinging member 42x swings about a rotation axis extending in a second direction. The swinging member 42x is made of a magnetically adsorbable material, such as metallic iron. The right end of the swinging member 42x is the adsorption end 421x and the left end is the contact end 422x. The swing center of the swinging member 42x is located between the adsorption end 421x and the contact end 422x in the second direction. The electromagnet 44x is arranged below the adsorption end 421x of the swinging member 42x. In a third direction, the swinging member 42x is arranged between the detected member 4x and the electromagnet 44x. The contact end 422x is used to contact the detected member 4x.

[0591] The on-off component includes a conductive sheet 33x. The conductive sheet 33x is fixedly mounted on the first cover 111. The conductive sheet 33x includes a first on-off control portion 731x and a second on-off control portion 332x. The first on-off control portion 731x is arranged at the front end of the conductive sheet 33x. The inclination direction of the first on-off control portion 332x is set such that the front end is more to the left than the rear end. The second on-off control portion 332x is arranged at the rear end of the conductive sheet 33x. The inclination direction of the second on-off control portion 332x is set such that the front end is more to the right than the rear end.

[0592] The conductive sheet 33x contacts and is electrically connected to the right ends of the second wire 32x and the third wire, wherein the first on-off control portion 731x contacts and is electrically connected to the right end of the second wire 32x. On the right end face of the stirring gear 24x, there are provided a first control protrusion 241x, a second control protrusion 242x, and a third control protrusion 243x protruding to the right. An extension portion 2431x extending in a direction away from the rotation axis of the stirring gear 24x along the radial direction is further provided at the right end of the third control protrusion 243x. The end of the extension portion 2431x in the radial direction is compared with the ends of the first control protrusion 241x and the second control protrusion 242x in the radial direction

[0593] Farther from the rotation axis of the stirring frame. The first on-off control part 731x is located on the movement paths of the first control protrusion 241x and the second control protrusion 242x, and the second on-off control part 332x is located on the movement path of the extension part 2431x.

[0594] In the factory preset state, the first control protrusion 241x abuts against the first on-off control part 731x, causing the conductive sheet 33x to elastically deform and bend, so that the conductive sheet 33x is in a state of being disengaged from contact with the second wire 32x and not electrically connected, so that the circuit between the battery 45x and the electromagnet 44x is open, and the electromagnet 44x is not powered on and stops working.

[0595] Then, as the stirring gear 24x rotates clockwise, the first control protrusion 241x rotates with the stirring gear 24x and disengages from the first on-off control part 731x. At this time, the conductive sheet 33x elastically recovers and comes into contact with and is electrically connected to the second wire 32x again, so that a circuit is formed between the battery 45x and the electromagnet 44x to supply power to the electromagnet 44x, causing the adsorption end 421x of the swing member 42x to be adsorbed, and the adsorption end 421x of the swing member 42x swings downward and the contact end 422x swings upward, thereby pushing the detected member 4x to move upward from the non-detection position to the detection position.

[0596] Then, as the stirring gear 24x rotates, the second control protrusion 242x abuts against the first on-off control part 731x, causing the conductive sheet 33x to elastically deform again and disengage from the second wire 32x, so that the circuit between the battery 45x and the electromagnet 44x is open again. At this time, under the elastic force of the reset elastic member 43x, the detected member 4x moves downward from the detection position to the detected position.

[0597] Then, as the stirring gear 24x rotates, the second control protrusion 242x disengages from the first on-off control part 731x, and the conductive sheet 33x elastically recovers and comes into contact with the second wire 32x again, so that a circuit is formed between the battery 45x and the electromagnet 44x, causing the electromagnet 44x to adsorb the adsorption end 421x of the swing member 42x again, and the contact end 422x of the swing member 42x pushes the detected member 4x upward, causing the detected member 4x to move upward from the non-detection position to the detection position, thus completing the detection process.

[0598] Subsequently, as the stirring gear 24x rotates, the third control protrusion 243x contacts the side surface of the second on-off control part 332x to drive the conductive sheet 33x to rotate, so that the first on-off control part 731x rotates away from the moving paths of the first control protrusion 241x, the second control protrusion 242x, and the third control protrusion 243x, preventing the electromagnet 44x from being energized again after the detection is completed and causing the detected part 4x to move again and wrongly trigger the detector.
